Smallville's Tom Welling Joins Arrow's Crisis On Infinite Earths Crossover

It's happening. It's actually happening. When news about the guest stars joining the Arrow-verse Crisis on Infinite Earths crossover started being announced, there was one name many fans were waiting to join the conversation. While it's exciting to see the likes of Burt Ward (Batman), Kevin Conroy (Batman: The Animated Series), and Tyler Hoechlin (Supergirl) lining up to appear in the event, what about the cast of Smallville?

The series, which starred Tom Welling as a young Clark Kent, ran for 10 seasons between 2001 and 2011. It also introduced a new era of superhero TV shows, which continues to thrive on The CW today. And now, the Arrow-verse will be able to pay tribute to the show as TV Line reports that Welling will reprise his role as Clark Kent in Crisis. "For eight years, Arrow has stood on the shoulders of Smallville," executive producer Marc Guggenheim said in a statement. "Simply put, there would be no Arrow, and no Arrow-verse, without it. So when we first started talking about Crisis on Infinite Earths, our first, second and third priorities were getting Tom to reprise his iconic role as Clark Kent. To say that we're thrilled would be a Superman-sized understatement."

According to TV Line, Welling's appearance will show what became of Smallville's version of Clark in the years since the series ended. Welling won't be the only Superman in the crossover, though. Hoechlin will play his take on the character from Supergirl, while Legends of Tomorrow star Brandon Routh--who played the Man of Steel in Superman Returns--will suit up in the blue tights one more time as an older version of Clark.

The Crisis on Infinite Earths crossover will begin on The CW with the Sunday, December 8 episode of Supergirl. It will then continue on Batwoman (December 9) and The Flash (December 10), before winter hiatus. The event will conclude with episodes of Arrow Legends of Tomorrow, both of which will air on January 14.
