After Entertainment Weekly spilled the beans about Michael Rosenbaum not returning for the finale of Smallville, with an unnamed source saying he's done with it, word has come out rather quickly that it's not true and the actor is signed on for the series finale of Smallville to return to the role of Lex Luthor. Rosenbaum left the series back in 2008 to focus on his writing career but has been actively wooed for quite awhile now for a return of some sort in the final season and especially the finale if nothing else. According to Deadline Hollywood, everything got signed on the dotted line on Friday night, possibly spurred on a little more by all the reports that were out there dismaying the fans.
"It feels like the stars are aligning, literally. We couldn't be more excited about having Michael back," Smallville executive producers/showrunners Kelly Souders and Brian Peterson said. "And as far as the way he returns … there'll be no doubt about how Lex becomes the great rival in Clark Kent's life. He is the villain of the story."
Rosenbaum himself commented on the deal by saying, "I'm simply doing it for all of the fans out there who made Smallville the great success it is," he said. "I appreciate all of their passion, their relentlessness and even their threats. Ha ha. I can't wait to hug the old crew back in Vancouver one last time and see all of my old friends once again..... Oh, and for Lex to become the badass he's destined to be."
