I'm actually very surprised that effects or stunt heavy movies DIDN'T map out all of their scenes, almost shot for shot, ahead of time. Prevents costly post production or editing mistakes when they realize it is unclear that the hero got shot, or just who is fighting what, or that the 3 scenes of characters talking about toast are just too much.
Sorry but he's right. People can post all the interviews from "directors" (who are always currently under Disney's employ) who try to dispute this but these movies are directed by executives and VFX artist. Exact plot lines, action sequences, and specific shots are planned years before a single crew member is even hired. They just trace the outline with a pencil basically. They are expensive 2 hour TV show episodes. Their directors superfluous, their cinematographers extraneous. Their writers? Please.
The travesty and audience theft is when a major film starts shooting WHILE WRITING THE SCRIPT, has that ever worked out well?
