Some key "Legends of Tomorrow" cast and characters already carved their storyline in recently-concluded "The Flash" - "Arrow" crossover episodes.
Falk Hentschel's Carter Hall / Hawkman and Ciara Renée's as Kendra Saunders / Hawkgirl as well as their nemesis Vandal Savage (Casper Crump) were heavily featured in the latest episode of "The Flash" and "Arrow." After these episodes, they will transfer to a TV series of their own and they might take someone with them, someone that is pivotal to Barry Allen (Grant Gustin) and STAR Labs team.
Entertainment Weekly reported Carlos Valdes has joined "Legends of Tomorrow" cast and will reprise his role as the funny, genius Cisco.
"This week's epic Arrow-Flash crossover won't be the only time you'll see these worlds collide this season. EW has learned exclusively that Carlos Valdes is slated to appear on the upcoming midseason spin-off DC's Legends of Tomorrow," the entertainment website wrote.
Although he will play the same role, Valdes revealed LoT Cisco will be different from what people sees in "The Flash."
"I did get to do an interesting take on this character on Legends of Tomorrow," he told EW.
Given the fact that "Legends of Tomorrow" is about time travel, there is a high chance Cisco LoT version is from the future or the past. His case might be the same with Connor Hawke, Oliver Queen's son in the comics, who reports say is also part of the line up.
In another interview, showrunner Greg Berlanti revealed they had to re-shoot some episodes because they need to integrate new characters into some scenes.
"We had already started to shoot the first couple of episodes of Legends before we shot these episodes," he told The Hollywood Reporter. "We also knew that there were characters who had been on Flash and Arrow that we were also shooting out of those respective shows before we went into shooting Legends to then have to come back and do the introduction of some of the characters here."
Aside from Valdes, other "The Flash" who are part of "Legends of Tomorrow" cast are Victor Garber, Wentworth Miller, Dominic Purcell, and Franz Drameh.
