Smallville's Tom Welling says he and Michael Rosenbaum are working on an animated sequel series to the hit CW superhero drama.

Smallville star Tom Welling confirmed he and co-star Michael Rosenbaum are working on an animated continuation of the fan-favorite CW superhero series.

"Michael Rosenbaum and I are actually working on an animated series to bring those characters back to life, and use as many of the original cast members as possible," Welling said in a Cameo message. "Don't tell anybody, though. It's a secret, we're still working on it."

Created by Alfred Gough and Miles Millar, Smallville premiered on The WB (now The CW) in 2001 and ran for 217 episodes across 10 seasons, ending in 2011. The show starred Welling as a young Clark Kent and followed his formative years in the Kansas town of Smallville as he developed his abilities and made both friends and enemies along the way. Chief among them was Rosenbaum's Lex Luthor, who began as one of Clark's best friends and slowly transitioned into the Man of Steel's most cunning foe. It also featured appearances from such notable DC heroes as Aquaman, Green Arrow and Black Canary, among others.

The show famously had a "no tights, no flights" edict, meaning Welling's Clark Kent never donned Superman's iconic costume or flew over the course of Smallville, save for the series finale. However, the story continued in comic book form with Smallville Season 11, which picked up where the finale left off and even introduced Batman into the show's continuity.

Welling famously reprised his role as Clark Kent alongside Erica Durance's Lois Lane for the Arrowverse's "Crisis on Infinite Earths" crossover in 2019, where it was revealed that he gave up his powers to live a normal life.
