Of course it’s just my opinion, but the most realistic and best performance of a man who stutters is in the movie a “A Fish Called Wanda. You can look it up… it’s an incredible cast, and a funny, amazing movie. I forget the actor who played the character that stuttered, but it’s incredibly realistic. As a sidenote, I have always felt incredibly uncomfortable watching a movie with friends where there is a character who stutters. It’s as if I’m on the TV myself.
