Gotham -- Smallville

It's happening! Smallville star Tom Welling is back as Clark Kent for "Crisis on Infinite Earths," this year's five-show Arrowverse crossover. According to longtime Arrow executive producer Marc Guggenheim, this epic return was his utmost priority.

“For eight years, Arrow has stood on the shoulders of Smallville. Simply put, there would be no Arrow, and no Arrowverse, without it,” Guggenheim told Deadline. “So when we first started talking about 'Crisis on Infinite Earths,' our first, second and third priorities were getting Tom [Welling] to reprise his iconic role as Clark Kent.

Back in August, longtime Arrowverse producer Marc Guggenheim revealed he was actively seeking a Smallville alum to join "Crisis on Infinite Earths," saying, "It's such a big part of DC TV history. I would love to have at least one Smallville character in the crossover... the whole reason we started talking about the crossover as early as we did this year was to give us time to have all those conversations."

"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.
