Falk Hentschel will play Carter Hall alongside already-announced Ciara Renée as Kendra Saunders a.k.a. Hawkgirl. Legends of Tomorrow is using the reincarnation origin, tying the pair to ancient Egyptian mythology.
Casper Crump has been cast as Vandal Savage, the main villain for Legends of Tomorrow. As in the comics, Savage is an immortal, who has manipulated history for millennia as he moves toward world domination. (In some versions, he’s been various famous conquerors throughout history, faking his own death and then starting again. In others, he’s been the power behind various thrones.)
Both Hawkman and Vandal Savage will make their first appearance in this season’s Arrow/Flash crossover before moving on to Legends.
