Another Superman has joined "Crisis on Infinite Earths."
According to Deadline, Smallville star Tom Welling will reprise his role as Clark Kent in this year's five-show Arrowverse crossover. He joins Tyler Hoechlin and Brandon Routh, who will also play Superman in the event.
Welling's character will pick up almost ten years after the events of Smallville. At the time of writing, it is unclear if Welling will don the Man of Steel's iconic costume -- something that the actor famously shut down for the Smallville series finale. This will be the first time he has returned to the character since May 2011.
Back in August, longtime Arrowverse producer Marc Guggenheim revealed he was actively seeking a Smallville alum to join "Crisis on Infinite Earths." Given this news, he made good on that promise, despite Welling and Michael Rosenbaum's recent comments that no one had spoken to them about it.
"Crisis on Infinite Earths" already has a star-studded list of guest stars. Batman: The Animated Series star Kevin Conroy, Black Lightning's Cress Williams, Batman 1966 star Burt Ward, Legends of Tomorrow's Jonah Hex, The Flash triple-threat John Wesley Shipp and "Elseworlds" alums Tyler Hoechlin and Elizabeth Tulloch are among those appearing the crossover. Routh has been confirmed to appear as Kingdom Come Superman.
"Crisis on Infinite Earths" begins Sunday, December 8 at 8 pm ET/PT on Supergirl, then continues in Batwoman on Monday, December 8 at 8 pm ET/PT and in The Flash on Tuesday, December 10 at 8 pm ET/PT. After the winter hiatus, the crossover will conclude on Tuesday, January 14 in Arrow at 8 pm ET/PT and in DC's Legends of Tomorrow at 9 pm ET/PT.
