Ed Harris as Wilford

Ed Harris plays Wilford, the man who owns and runs the train. "You don’t see me until the end," he told Collider. "There’s a revolution going on with all the poor people that starts in the back of the train and moves its way forward. They finally get up to the front where I’m at."
