It's really big deal to the fans that Michael Rosenbaum is returning to the role of Lex Luthor in the final season of Smallville. There's no way the show could have ended properly without him. Now here we have our first look at the villain and the hero facing off for the first time in years. I hope it turns out to be an epic end to a very entertaining series. The two hour season finale is set to air on May 13th.
