I have only seen two movies where there were guys who had stutter (they weren't a protagonists, just some side characters) i've watched these movies so long time ago, but i still remember it, one had a really bad stutter, but the most amazing thing for me was that he was so happy, his smile, his laugh i was really amazed by it (despite the fact that this is just an actor witch doesn't have stutter) the main character asked him when did he get a stutter, and he answered "in childhood" relatable isn't it? In second movie there also was a guy who had stutter on war, but he doesn't have any problem with that, he just speaks and doesn't care about people's opinion Tbh the only why I think there is no film with protagonist who has stutter, it's because no one would like to watch a person who stuttering Wait, i have remembered "It" in this film there was a teenager who had stutter, and also he had overcome it in the film, you can maybe watch it, if you are interesting in it I apologize if i have made some mistakes, it's just 1AM for me and i am a little tired
