Dumb and Dumber is one of my favorite comedy movies of all time. I know that this is not a popular opinion, but I really think that Jim Carrey is the greatest actor. I know, I know, he just does a lot of comedy, but that is not all that there is to him. He has a lot of films that are also in the dramatic genre, I suggest that you go and check them out. Jim Carrey is such an amazing actor.
