Casper Crump is one of the most recent to join "Legends of Tomorrow" cast and the pressure on him to deliver is quite big.
He is playing Vandal Savage which is the main villain of the upcoming TV series spun from "The Flash" and "Arrow."
This will be the first time Vandal Savage will appear in a live action project and executive producer Phil Klemmer said him being immortal is one of the best reasons why the characters from the good side will have a hard time.
"With Vandal, with any villain, the trick is always to find somebody commensurately evil or formidable," Klemmer, known for his works on "Veronica Mars" and "Chuck" said in an interview with Comic Book Resources.
"We have an ensemble of eight-plus heroes -- you have to come up with a version of the antichrist if you want it to feel like it's anywhere close to being an even challenge between the black hats and the white hats; although in truth most of our guys are sort of gray hats. Coming up with an immortal seemed like the only way that we could have a bad guy who matched our team."
A villain as good as the hero is a necessity in any comic book TV shows or movies. Another reason why all eyes in on Crump is because he is one of the few "Legends of Tomorrow" cast members who hasn't appeared in any episodes of "Arrow" and "The Flash".
People will get a peek of him though through the upcoming "Arrow" - "The Flash" crossover episode which Klemmer says is "kind of nuts."
"What we've planned is kind of nuts," he said. "There were crossover episodes last season, and now we've doubled-down on the notion of trying to integrate the worlds of the three shows. It's such an awesome idea on paper, but logistically, when you try to figure out what it means for these poor actors trying to appear on three shows at once -- time travel is something that makes your head want to explode, but the idea of trying to find how to make the worlds of all three shows coordinate? It probably will kill us. Or kill one of the actors. [Laughs]"
The show is expected to air early next year. Aside from Crump, other members of "Legends of Tomorrow" cast are Brandon Routh, Caity Lotz, Wentworth Miller, Dominic Purcell, Victor Garber, Ciara Renee, and Franz Drameh.
