Dutch/Danish/Swedish? movie where these guys had a roommate with social anxiety and he had a really cool name. His name was two words, like Sven Anders or something … He was afraid to leave his apartment complex, and one of the big events was when he got the courage to step onto a subway/train car leaving his locale.
“Elling” maybe? One of the guys is called Kjell Bjarne…
