Josh Hartnett as Superman? Yup, he's another actor who nearly donned the red cape. It was yet another version of Superman:Flyby that never got off the ground. In Hartnett's would-be version, director Brett Ratner was attached. This was back in the early 00's, when Hartnett was a viable leading man and before Ratner laid waste to the X-Man franchise with the lackluster X-Men 3.
