I thought I'd combine these 3 shows into one post because they essentially share characters/actors and the universe.
Here is the first look at DC's Legends of Tomorrow:
Here you'll see Brandon Routh as Ray Palmer/The Atom, Victor Garber as Martin Stein, Wentworth Miller as Leonard Snart/Captain Cold, Dominic Purcell as Mick Rory/Heat Wave, Ciara Renée as Kendra Saunders/Hawkgirl, Arthur Darvill as Rip Hunter, and Caity Lotz as somehow-returned-from-the-dead Sara Lance. Now in White Canary form.
The official synopsis for Legends of Tomorrow is as follows: “Having seen the future, one he will desperately try to prevent from happening, time-traveling rogue Rip Hunter (Darvill) 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?”
Should've known they'd also release a trailer:
