I kind of doubt that they would get anyone else from the movie to appear--although the guy that played the son is probably available (he's been on YOUNG & THE RESTLESS)--and it's mainly because Routh is right there, so how could they pass up the chance to give him one last hurrah as Superman. But from what Brandon has said, it sounds like for him as an actor he'll be closing out the story of the Superman he played on the big screen.

It just shows how much WB is willing to give the CW for this big event. Looking at how they've vetoed so many stories and characters in the past, for them to let the CW use one of their motion picture properties is a big deal. It's one thing if it's Tyler Hoechlin playing an off-brand Superman, but it's quite another thing when it's Brandon Routh himself playing the Man of Tomorrow.

I expect to cry a lot before this event is over. I'm a pretty sentimental guy, unfortunately.
