During an interview with Legends of Tomorrow executive producer Phil Klemmer, DC Legends TV reports that they learned Hawkman will be a series regular on the show...and that his relationship with Hawkgirl will remain very inspired by Geoff Johns' JSA and Hawkman stories:
"The way we’ve imagined them is that they’ve obviously been reincarnated through the ages together, but the fact that he remembers their previous lives and she doesn’t… it gives them very much like a Bogey and Bacall sort of [relationship]," Klemmer said. "Yeah. Exactly! They’re constantly fighting, and the fact that they’re destined to be in love is something that seems impossible to her."
When heroes alone are not enough… the world needs legends. Having seen the future, one he will desperately try to prevent from happening, time-traveling rogue Rip Hunter is tasked with assembling a disparate group of both heroes and villains to confront an unstoppable threat — one in which not only is the planet at stake, but all of time itself. Can this ragtag team defeat an immortal threat unlike anything they have ever known? DC’S LEGENDS OF TOMORROW stars Victor Garber (“The Flash,” “Alias”); Brandon Routh (“Arrow,” “Superman Returns”); Arthur Darvill (“Doctor Who”); Caity Lotz (“Arrow”); Ciarra Renee (“Pippin”); Franz Drameh (“Edge of Tomorrow”); with Dominic Purcell (“The Flash,” “Prison Break”); and Wentworth Miller (“The Flash,” “Prison Break”).
