On a movie set, the director has a huge amount of authority. It’s been baked into the culture for about a hundred years that the director is one step below God. A studio treats films as investments, but they also hire a director and (mostly) get out of the way. Sure, producers do meddle, but it’s nowhere close to the same amount as with games – and all the meddling is still pointed at the director, not the crew. I think this limits the damage that can be done.

Also, the film industry has strong unions. Most of the abuses in game dev simply aren’t allowed. I suspect that the horrible culture of game dev can cause developers to stop caring, which bleeds through to the final product, and that won’t happen to the same extent for movies.
