Robert Zemeckis has been fueling our imaginations and moving our hearts for years with movies like BACK TO THE FUTURE and FORREST GUMP, and his new movie WELCOME TO MARWEN is all about the power of our own imaginations. Based on the documentary MARWENCOL, the movie is about a man named Mark Hogancamp (Steve Carell) who was savagely beaten by thugs and lost most of his memory.
