Behind the Scenes of the Arrowverse Crossover 'Crisis on Infinite Earths' (PHOTOS)
A Crisis is coming to the Arrowverse — and it's going to take quite a few superheroes (including familiar faces from past series) to stop it.
And it's not just those from Arrow, The Flash, DC's Legends of Tomorrow, Supergirl, Batwoman, and Black Lightning who will be stopping by to help. Among the special guests appearing are Smallville's Tom Welling (Clark Kent) and Erica Durance (Lois Lane).
The actors have begun posting photos from the sets of the five-part event, and you can click through the gallery above for a sneak peek.
