Superman is not only an icon of comic books but also one of TV and cinema, as the beloved hero has appeared on the big and small screens numerous times over the years. Within the live-action realm, several actors have brought him to life, from George Reeves and Christopher Reeve to Henry Cavill and Tyler Hoechlin. There have been some interesting casting choices and, as it so happens, another notable star could’ve played the Man of Steel. Paul Walker was once presented with the opportunity to take on the role but ultimately turned it down.
