First Look At DC's Legends Of Tomorrow
We see Arthur Darvill (Rip Hunter), Ciara Renee (Hawkgirl), Victor Garber (Martin Stein), Caity Lotz (unknown), Brandon Routh (Ray Palmer/The Atom), Wentworth Miller (Leonard Snart/Captain Cold) and Dominic Purcell (Mick Rory/Heat Wave).
It appears from the image that Lotz's character may be from the future, perhaps teaming with Rip Hunter.
Update: The CW has confirmed Caity Lotz is playing White Canary.
DC's Legends Of Tomorrow will premiere in 2016.
Update #2: with synopsis:
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?
