You could file a complaint yourself about workplace hostility, that the video violates the "working together guidelines", with the graphic content.

Although you are not required to watch that movie, you are required to work in the environment where customers do watch it. That would include deadheading next to someone that might watch it, or a non rev- flight where your kids are exposed to it.

Some movie content does slip by the screeners. Years ago I complained about the content of a couple movies.

Believe it or not, the company actually took the complaint seriously and looked into it. The changed some of the parameters of what is acceptable with the company that screens the movies for them.
