"I'm delighted to return for the series finale," the interview with Rosenbaum on TVLine.com states. "I'm simply doing it for all of the fans out there who made Smallville the great success it is. I appreciate all of their passion, their relentlessness, and even their threats. Ha ha."
Kelly Souders and Brian Peterson, executive producers of Smallville say of Rosenbaum’s return, “It feels like the stars are aligning, literally. We couldn’t be more excited. 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.”
On the idea of Luthor’s character evolution, Rosenbaum states that he is excited for “Lex to become the bad-ass he’s destined to be.”
After 10 seasons, the Smallville team has decided to call it quits and hang up their superman capes. As such, they have been calling on Smallville alumni to give the show a memorable send-off. The return of Rosenbaum fits this trend, and for fans, it will be exciting to see the end of a long-running character arc.
The two hour series finale will air on May 13th.
