Lex Luthor is back.
After insisting last week that he wouldn't return for the May 13 series finale of "Smallville," Michael Rosenbaum has had a change of heart.
The CW announced on Wednesday that Rosenbaum, who played Clark Kent's arch nemesis through the first seven seasons of the series, which debuted in 2001, will appear in the final episode.
“I’m delighted to return for the series finale. I’m simply doing it for all of the fans out there who made 'Smallville' the great success it is," Rosenbaum said in a statement. "I appreciate all of their passion, their relentlessness and even their threats.
