Fan Casting ''Where have you been, Bruce??'' in Batman And Robin: The Caped Crusaders

In the ending scene for the film, upon returning to his home universe with the Joker in his grasp, the Bruce Wayne of Earth-12 is immediately greeted by a man not much younger than him wearing a grey suit and a pair of glasses, who asks, ''Where have you been, Bruce??'' to which Bruce responds, ''What's the problem, Clark?'' The younger man then hastily replies to him, saying, ''Waller's hiding something from the League.. I need you if I am to get to the bottom of it!''
