Answer 1

I used to wonder just how much of an influence a director has, then I saw a couple of gifted actors in a really bad film. It seemed to me that it wasn’t the storyline or dialogue, the actors themselves just didn’t appear very convincing, rather wooden. So if better performances weren’t evoked or the issues weren’t resolved in post production it seems the director was responsible.
