After several characters from The CW's midseason spinoff DC's Legends of Tomorrow appeared in the Arrow and The Flash crossover earlier this week, the network has revealed a new poster featuring all of these heroes assembling together. The poster features Brandon Routh's Atom, Caity Lotz's White Canary, Arthur Darvill's Rip Hunter, Wentworth Miller's Captain Cold, Dominic Purcell's Heat Wave, Falk Hentschel's Hawkman, Ciara Renee's Hawkgirl, Victor Garber's Dr. Martin Stein and Franz Drameh's Jay Jackson. All of these characters will come together to fight the immortal Vandal Savage (Casper Crump), who isn't featured in this poster.

We reported last month that DC's Legends of Tomorrow premieres on Thursday January 21 at 8:00 PM ET. In DC's Legends of Tomorrow, 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 the planet is at stake, but all of time itself. Can this ragtag team defeat an immortal threat unlike anything they have ever known?

Based on the characters from DC Comics, DC's Legends of Tomorrow is from Bonanza Productions Inc. in association with Berlanti Productions and Warner Bros. Television, with executive producers Greg Berlanti, Marc Guggenheim, Andrew Kreisberg, Phil Klemmer, Chris Fedak and Sarah Schechter serve as executive producers. Glenn Winter directed the pilot episode, from a script by Greg Berlanti, Marc Guggenheim, Andrew Kreisberg.

The show's main villain is the immortal Vandal Savage (Casper Crump), who made his debut in the Arrow and The Flash crossover event earlier this week on The CW. We reported in September that Stephanie Corneliussen has signed on to play the DC Comics character Valentina Vostok, a.k.a. Negative Woman, and another report from October revealed that the show is casting for Connor Hawke. In the Arrow comic books, Connor Hawke is Oliver Queen's son, although that aspect of the comics will be discarded for the TV version.

Greg Berlanti, Marc Guggenheim, Andrew Kreisberg, Phil Klemmer, Chris Fedak and Sarah Schechter serve as executive producers. Glenn Winter directed the pilot episode, from a script by Greg Berlanti, Marc Guggenheim, Andrew Kreisberg.
