This is a mesh of one commentary with the director and another with the cast edited together. I thought the cast one was fun and entertaining but once the director came on, all momentum was gone. I wished this had a track with just the cast.

Three writers, maybe four but one introduces himself as a technical consultant. Two of them are writing partners and the others never have met before. Ayer probably has the most to offer and has gone on to direct several films. They share insights about the writing process in the film industry, as an example that 8 writers were involved over the years in the many versions of the script for this film. They offer their thoughts on working with actors in SWAT and in previous films, Training Day and American History X. Much of the commentary is a discussion of ideas that were jettisoned from their drafts for various versions for this film, or other ideas they incorporated after the studio pitched concepts to them. Given that the film was in development for many years, real world events made the studio skittish about depicting certain acts of terrorism, and the nationality of the villian changed. More generally, they delve into the difficulties of succeeding in screenwriting and do offer some tips at writing scripts. They talk about the nuances of MPAA ratings, the importance of doing research for films and how the internet has streamlined the research process. They talk a bit about visiting sets as writers and how it has been rare for most of them. Towards the end of the film, they tend to just watch and have less to say.
