It has been confirmed that Tom Welling will be returning as Clark Kent/Superman from the hit series Smallville; he will be joining Brandon Routh’s Superman, Black Lightning, Kevin Conroy’s Batman, Burt Ward, The Monitor, and Anti-Monitor and much more. According to the Hollywood Trade, the crossover will “address what happened to the Character ten years after Smallville.” But for now, we’re going to have to wait and see if his Superman will appear.
“For eight years, Arrow has stood on the shoulders of Smallville. Simply put, there would be no Arrow, and no Arrowverse, 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.”Marc Guggenheim
“Crisis on Infinite Earths” will crossover Arrow, The Flash, Supergirl, DC’s Legends of Tomorrow and Batwoman in a five-episode event, with three episodes airing in December and the remaining two airing in January.
