Has some similarities to Forty Year Old Virgin, from 2005, which also starred Carell. A tale of a guy lacking confidence. Who works through his issues using small figurines. Welcome to Marwen seems to be a remake of Marwencol (2010), an an actual autobio by.... Mark Hogancamp himself! In Welcome to .... Carell plays Mark Hogancamp, who is represented by the action figure Captain Hogie when he's filming. Confused yet? Clearly, the human Hogancamp has PTSD or some emotional issues afer "the attack", and building/filming the action figures is how he deals with it; fun miniature cities and details. Of course, they are playing "Crazy", by Patsy Recline in the background. Marwencol has an entry in wikipedia, where you can find Mark's actual story, and what led him to build the miniature city. Neighbor Nicol (Leslie Mann) is very sweet, but her husband is a jerk. Leslie Mann was also in Forty Year Old Virgin. Friend Wendy is played by Stefanie von Pfetten. It's a cute, heartfelt story. Directed by Robert Zemeckis, who didn't direct either of the other films discussed earlier.
