The CW’s potential new Flash and Arrow spin-off is slated to feature a mashup of DC Comics heroes and villains that aims to take our generation’s super series to the next level.

The untitled drama—which is being developed by Arrow and Flash executive producers Andrew Kreisberg and Greg Berlanti, as well as Arrow boss Marc Guggenheim and Sarah Schechter—is tentatively slated to star Brandon Routh (Ray Palmer/The Atom), Wentworth Miller (Leonard Snart/Captain Cold), Victor Garber (Martin Stein/Firestorm) and Caity Lotz, though it’s unclear whether she’ll be portraying a new role since her Arrow character, Sara Lance, died earlier this season.

“For me, it honors all of the great team up movies, whether it’s Ocean’s Eleven or whether it’s the superhero books,” Berlanti tells EW. “That’s what it’s about. If you go back to the old westerns, there would be The Lone Gunman, but there would also be The Magnificent Seven. It’s very much in the spirit of those kinds of movies and shows.”

Berlanti—who is also executive-producing CBS’ Supergirl pilot with Kreisberg, Schechter and Ali Adler—stresses that the new project would be quite different than what we’re used to. “I only want to do them when I know that they’ll feel distinct from the other shows we’re doing,” he says. “This is really its own thing.”

One of the main burning questions after the project’s announcement was why Robbie Amell was missing from the cast list, considering he makes up the other half of Firestorm, Ronnie Raymond. Unfortunately, it sounds like bad news could be on the horizon as Berlanti admits there is a particular reason for his absence, but “I can’t say why.”

The new super drama, which is not part of the current pilot season, was first mentioned by CW president Mark Pedowitz at the Television Critics Association’s semi-annual press tour in January. Get more on that here.
