Stan Lee Rides Every Train
Stan Lee's cameo in this one isn't just his little shop scene. The 180-odd animators on the film were all diehard Marvel fans and every single one of them wanted a shot at drawing him, so the directors let them sneak him in wherever they could. Pause the movie any time a subway train rattles past in the background and there's a very good chance you'll spot him sat inside it. It ended up being his last ever voice role.
