James Gunn has confirmed one classic DC character who will appear in Superman: Legacy, as he plans to include Jimmy Olsen. The writer and director of the first DC Universe movie has the responsibility of relaunching Superman after Zack Snyder's take on the character played by Henry Cavill. Details on Superman: Legacy are still sparse, but it is known that it will not be an origin story for Clark Kent. Instead, the movie will explore his life on Earth as he grapples with his Kryptonian heritage and what his parents on Earth taught him. Who Superman will fight and who will join him on the adventure has not been revealed.
