What is happening to Second Unit Directors?

10 February '20 16 Comments on What is happening to Second Unit Directors?

Something strange is happening to the role of second unit director… and I don’t know why.

I have crunched the data in a number of different ways and spoken to a fair number of industry insiders but I remain none the wiser as to what’s causing the trend we’ll see today.

I don’t normally publish results I can’t explain, but in this case, I’m stumped.  My hope is that intrepid readers will have theories I can test or insights into what’s shifting within the industry.  (I’ll be sure to update this article if I do ever find a satisfying answer).

Let’s start by familiarising ourselves with the role of second unit director and then we can turn to the mysterious trend.

What is a Second Unit Director?

A Second Unit Director is, well, the director of a film’s second unit.  The main unit is what most people think of when they picture a film being shot.  The film’s main director is working with the cast to shoot the main scenes of the movie.  But this is often not the only unit on a production.   There may be additional units which specialise in filming tricky elements (underwater, miniatures, aerial, stunts, etc) or units designed to save time or money by standing in for the main unit.

In some cases, a second unit will be picking up incidental shots which wouldn’t be worth paying a full main unit to do, such as establishing shots of locations, extreme close-ups,  crowd scenes – basically anything that doesn’t feature the main cast.  However, that’s not always the case.  John Mahaffie, who directed the second unit on the three Lord of The Rings films, estimated that 20% of his work was with the main cast, with the other 80% being things like “guys in black hoods with black horses chasing [Gandolf] on a white horse“.  He described his work thus:

For all intents and purposes, we operate as a stand-alone unit—independent. And my role as a second-unit director is, first of all, to be in tune with the style of the main-unit director and the action requirements, and to be intuitive as to his priority for the look of the film and how the film is to go together. But then once I’ve taken that…I’m on set with a full crew of 120, 150 people.

Second units are often called in to handle complex physical challenges such as special effect sequences.  On action films, this could mean that the second unit director was behind a fair chunk of the final screentime and perhaps most of the film’s trailer.  The second unit director reports to the film’s main director and is working to match their vision for the film. However, it’s perhaps not surprising that when Casino Royale was released, many people noticed the similarities of the action to the preceding The Bourne Identity, as the two films shared the same second unit director, Alexander Witt.

In other cases, the second unit directing credit may go to someone who shot some pick-ups, re-shoots or a single scene.  In the Marvel cinematic universe, some directors are credited as a second unit director for shooting the post-credits preview of the next movie, on which they are the main director.  One example is Joss Whedon who received one such credit on Captain America: The Winter Soldier for a scene he had shot during his time at the helm of The Avengers movies.

In conducting this research I was surprised to see that some rather famous names have second unit credits.  For example, Steven Spielberg has received four credits as a Second Unit Director (including on Star Wars: Episode III – Revenge of the Sith) and Peter Jackson has two (including on The Adventures of Tintin: The Secret of the Unicorn).

Now that we know the role of a second unit director we can turn to the data to see what’s happening over time.

What’s happening to Second Unit Directors?

In 2006, a third of all movies in US cinemas credited a second unit director, whereas by 2018 this had fallen to under a fifth.

This decline surprised me as I couldn’t see what change in the industry would precipitate fewer films needing a second unit.   So I set about probing the data to locate the cause.

Is this due to a greater number of films without second units?

My first thought was that the increase in the number of films released each year was flooding the market with smaller films (more on that here). Smaller, independent titles are less likely to have the required budget for a second unit.

However, when we isolate just the top 200-grossing movies of each year, we can see that there remains a decline.

My next thought was that perhaps the types of films were changing, moving away from films that require additional units.

In which genres are Second Unit Directors more prevalent?

The likelihood of a film employing a second unit director differs significantly by genre.  Fewer than a fifth of dramas and romance films have employed a second unit director (2000-18) whereas it’s close to two-thirds of adventure films.

Could a shift in genre production be behind our missing second unit directors?

No. The decline in second unit directors is to be found across all major genres, albeit to varying degrees.  The chart below shows two five-year periods – 2000-04 and 2014-18.  The biggest drops are among horror and thriller movies, whereas the most resistant genres are sci-fi and adventure movies.

And in some of the genres which employ many such directors, the decline is rather stark.  The chart below illustrates the picture for action movies.

Other possible causes

At this point, I was stumped and so reached out to a number of working second unit directors. I’m grateful to everyone who gave suggestions.

A couple of interesting theories that came up, and which I have investigated with the data, are:

  1. Falling budgets. The average production budget of horror and thriller movies has been falling rather sharply (more here) in recent years, however it is impossible to say whether this is causation, correlation or coincidence.  Across all movies, budgets have actually been rising over the past six years and so this can’t explain the wider trend for fewer second unit directors.
  2. First-time directors. One 2nd unit director suggested that it’s a symptom of new types of directors getting into the industry who are less likely to want to work with a 2nd unit director.  However, when I removed all the films directed by someone who had not previously directed a feature film, the decline remains in full effect.

So, having ruled out quantity, genre, budgets and first-time directors, I’m left without a working theory.  Perplexing….


This project is looking at live-action fiction feature films which were released theatrically in North America between 2000 and 2018, inclusive.  I focused on live-action films as I am considering the on-set role of second unit director.  Animated films do have “Unit Directors” (e.g. The Tigger Movie has seven) but this is an entirely different job.

I did not include films released in 2019 as some credits can take time to appear on online credits sites.  A few years ago, I studied the number of credits which the producers had not automatically added when listing their movies on sites like IMDb.  If the crew member in questions wishes to have their work recognised, they must manually apply to the site.  Based on today’s data, I calculated that around 6% of 2nd unit directing credits were not automatically added by the studio when they list their film.


Thank you to everyone who answered my questions for this piece. If you have a theory or suggestion of what’s happening, either leave a comment below or reach out to me directly.



  1. Very interesting data! Just brainstorming a few ideas that came to mind.

    Without having looked into it I wonder if improved and cheaper SFX technology could be replacing the second unit director? Is there a rise in SFX credits?

    With the biggest decline in horror/thriller I wonder, could the decline in second unit directors in horror/thriller films be due to changes in genre’s trends?
    Variables that come to mind are; “do horror/thriller films now have”:
    Smaller casts
    Single/fewer locations
    Realist/Minimalist style
    Auteur driven visions?

    Final thought is whether the second unit director is undergoing a re-branding? Are the second unit directors still working in a similar capacity under a new title? Is there a stigma they want to shake?

    Very interested to see if there is an answer, or if the best we can do is speculate!

  2. Just anecdotal: in watching the new James Bond behind the scenes footage, it looked like first unit was doing all the action/stunt scenes, interchanging stunt people with the stars when the scene was too difficult or complex. Same with MI:6.

    Could be that stars now want to at least try some of their own stunts.

    But I suspect, as always, there is a financial reason somewhere—mainly that the studios in particular are trying to shave costs in any way they can.

  3. Interesting data as always!

    The decline looks as though it mirrors the decrease in theatrical releases by the major studios. I think that’s worth looking in to: if major studio productions are more likely to have 2nd units than the likes of Lionsgate, STX, or ESMP, irrespective of budget etc., then that might account for the change, even if no-one has changed their production process.

  4. Did you examine 2nd Unit DoPs instead, or other names for units? You might investigate the trend of sending out a DoP with a Stunt Co-ordinator and calling it a Splinter Unit – that way stunt work gets done without an explicit 2nd Unit Director, which also saves money for Production (are 2nd Unit Directors above-the-line, ie. eligible for residuals?)

  5. Union rule change discouraging use of 2nd units or directors (intentionally or unintentionally).
    Same for tax breaks from local or national entity’s?
    Might check for geographic correlations.

  6. On some of the projects I have worked recently, it has seemed more common to actually let the shooting crew go out and shoot 2nd unit material without a director.

    I wonder if it might partly be something to do with the shift to digital?

    On digital it’s quick, it’s a bit more relaxed in terms of cost because it’s all on a memory card not film, so the crew shooting the second unit stuff just shoot multiple versions of whatever they’re asked to do. If the film stock was still an expense, the production wouldn’t allow that amount of waste so would send a director out with them instead.

    In addition, maybe it’s a perception thing – that because of the production boom, crews such as camera operators and DoPs are even more highly regarded than they ever used to be, so producers feel they can be trusted to shoot some 2nd unit material on their own, without a director.

    I also think that, where a director isn’t happy to let the crew go out and shoot basic 2nd unit material, such is the increase in production values of long form drama that the main directors are more precious about ownership of their work than ever. As such, they’d prefer to find a way to direct any “performance” 2nd unit sequences themselves.

    To summarise:

    Easy 2nd unit: shooting crew of sufficient calibre these days to shoot it themselves. Digital material cheaper to shoot so they can shoot multiple versions anyhow.

    Complex 2nd unit: shows so highly regarded with bigger budgets and production values that the director doesn’t want to share the creative input with others.

    Both of these factors would serve to reduce the instances of employing 2nd unit directors.

  7. Admitting that I do not work in films with large budgets and that some comments above may be directed at what I’m about to say, I’ll hypothesize. The cause of falling numbers of second unit directors is a combinaiton of such factors as more CGI/green screen, more rapid transfer of the day’s work from another site directly to the director as pure data, and more creation of scenes on a stage using both green screen and LED panels as opposed to working on location. In other words, technology has brought a lot work, which used to require a second person on site, straight to the film’s director allowing that person to assert creative control in a situaiton in which geography, time, and money used to mandate that it be given to a second person. I’ll guess that some directors are less than heartbroken by this trend. 🙂

  8. maybe worth to look into and compare with movie that credit A and B and eventually C camera with additional cameramen. These units that are in most situations are working next to the A camera are used on specific days to do “their own stuff” alongside their own schedule, or as splint units. And therefore have not a 2nd unit director attached.

  9. Stephen,

    Great study, I’ve had to put some thought into this because my assumption has been that there is more second units today.

    I think the onset of previz has played a role in this. In fact, I know of stunt coordinators that are reluctant to shoot previs because they are handing the director directions on how to shoot action.

    Why would a green director need a second unit when the entire action sequence is spelled out for them in the previz?

    This isn’t always the case but I know there is a lot more previz, both by VFX and Stunts, being done today.

    Would be curious if this helps shed any light on the issue. Unfortunately there’s no data on what projects have previz, it’s safe to assume today anything with action does.

    Lastly, a lot more stunt coordinators are becoming directors today (yay!) but even they rely on second unit directors. However some producers don’t allow it because they think that’s the reason they hired them in the first place.


  10. Hi Stephen .
    Definitely rise of VFX in production role , infact on some shows I’ve been on VFX super will direct 2nd unit . I’ve not worked with a second unit director myself board wise for a long time now .
    Great article as usual .
    Martin .

  11. Great article and very good comments. Many of these factors seem accurate, especially sending out a second DP, camera operator, a producer, vfx supervisor, or stunt coordinator with technology for rapid director approval at first unit. Likewise, as Bruce indicated, the overall decline in major studio big budget production numbers in general. Interesting, as a producer and second unit director it is a bit surprising but understandable for all the above reasons.
