Superman's greatest enemy has returned.
TVLine has debuted the first teaser trailer for the two hour series finale of "Smallville" with a tantalizing glimpse of Michael Rosenbaum back in the role for the first time in three seasons.
According to Rosenbaum, the script for the finale came together very quickly after he confirmed his intent to return.
“I called them up on like a Friday, saying: ‘Look, I want to do this, but I’ve [got] to film ['Breaking In'] — so I’m coming up [to Vancouver] next Thursday,’" related Rosenbaum to TVLine. "And they started writing!”
“We had already started breaking the finale,” added "Smallville" executive producer Kelly Souders. “But it was pretty easy and seamless to rev up that story faster.”
Although Rosenbaum's time on the set was relatively limited, he indicated that he enjoyed his long awaited return.
“I really didn’t want the day to end,” noted Rosenbaum. “Once you’re there, you always want more. Like, ‘Oh c’mon, this is fun. Write something else!’”
The CW has also released a longer synopsis for the series finale, with the promise of some "surprise guest stars."
The story of Clark Kent (Tom Welling) culminates in this epic two-hour series finale as Clark takes the last step to becoming the Man of Steel. With surprise guest appearances, nods to the first few seasons of the series and Michael Rosenbaum’s return as Lex Luthor, this final episode wraps up a decade-long story following one’s man’s journey to becoming the world’s greatest superhero. Erica Durance, Allison Mack, Justin Hartley, Cassidy Freeman, John Glover, Annette O’Toole and John Schneider also star. Kevin Fair directed “Finale Part 1,” which was written by Al Septien & Turi Meyer and Greg Beeman directed “Finale Part 2,” written by Brian Peterson & Kelly Souders.
The series finale of "Smallville" will air on Friday, May 13.
