What is his best film?
I haven't seen Green Book yet, but of what I have seen, I think his best film is Shallow Hal.
shareI'd say Green Book, it's a bit overlong and could have done with some cutting down but it's his best film imo.
There's Something About Mary and Dumb and Dumber are both comedy classic's. Also he didn't direct this film but wrote it and I think it's cult classic Outside Providence with Alec Baldwin and Amy Smart in it, if you haven't seen it well worth checking it out.
