Mark Hogancamp was nearly beaten to death by five men and spent 40 days in a coma. After recovering, he turned to an unusual form of therapy — building a massive World War II-era camp in miniatures. The camp had Mark's real-life friends, family, and even his attackers. From Robert Zemeckis, director of Forest Gump and Cast Away, Welcome to Marwen is based on the true story of Mark Hogancamp, and stars Steve Carrell and Leslie Mann. The film comes to theaters October 12, 2018.
