Arrow actor Stephen Amell revealed through a tweet TV Superman actor Tyler Hoechlin in a black Superman costume. The epic and very ambitious CW crossover that brings together Flash, Supergirl, and Arrow was originally announced as a set up to introduce Gotham and Batwoman ( to be played by Ruby Rose.) Then it was announced Superman and Lois Lane would be involved as well as the alien superintelligence known as the Monitor. The crossover is titled “Elseworlds” and will potentially bring multiverse problems to the doorsteps of our CW heroes.
As previously reported, this year’s Arrowverse crossover event will air Sunday, Dec. 9 through Tuesday, Dec. 11, comprised of the ninth episodes of The Flash (airing on a special night), Arrow and Supergirl (also airing on a special night). In addition to Hoechlin and Rose, guest stars include Grimm‘s Elizabeth Tulloch (as Lois Lane), Lost‘s Jeremy Davies (as Arkham Asylum doc John Deegan) and Cassandra Jean Amell (as Mr. Freeze’s wife, Nora).
