I think banter between an actor and director, (playful or otherwise) far removed from the set of the film goes a bit beyond the realm of critique and discussion of the actual film here.
Which is why I asked why I should care. Certainly in the context of this thread, it doesn’t matter in the slightest what the two guys think of each other.
If I knew they hated each other it would make me enjoy the movie a bit less. Technically the movie would be the same, but as a fan it feels better to know that the people involved had a good time. And it certainly seems like they did.
As long as one of them isn’t a literal criminal, I don’t care how they feel about each other on a personal level. The movie stands on its own.
