The CW is developing a superhero team-up series as a The Flash and Arrow spinoff that will feature four fan-favorite characters/actors from both shows, and three major DC characters that have never been seen on TV before. The network has been teasing an Atom spinoff for a few months now, but it looks like they’ve got something much bigger in mind after all. Brandon Routh, Caity Lotz, Wentworth Miller, and Victor Garber are set to headline the new series with Arrow creators Greg Berlanti, Marc Guggenheim and Andrew Kreisberg to executive produce.

Routh, Miller and Garber are said to return as their characters on The Flash and Arrow -Routh as Arrow‘s Ray Palmer/The Atom, Miller as The Flash villain Leonard Snart/Captain Cold, and Garber as Flash‘s Dr. Martin Stein – with Lotz’s character as yet unconfirmed. It’s possible that Lotz could be playing a new character given her Canary’s untimely demise. However, since the other cast members are returning as their established characters it would be a very strange choice, and would put a big strain on the audience’s suspension of disbelief.

Deadline reports that the series is not set for this pilot season, but given the stars and creative talent behind the project, as well as the massive fan following and warm critical reception for both The Flash and Arrow, it might go straight to series with a possible midseason premiere next year. The project is still very early in development, so it’s possible (and pretty likely) that other characters from either show could crossover.

As for the three new “major DC” characters, the two existing series have burned through a lot of characters from the DC Comics universe, but now that the DC cinematic universe has cast their own actors as the same characters in the CW shows (and definitively separated itself from the TV universe in the process) the door is wide open for some of DC’s most beloved and well known characters to make an appearance.

As a big fan of what Kreisberg, Berlanti, and Guggenheim have done with their televised DC universe so far, especially The Flash, I’m excited to see where this series could go. The cast is excellent, and Caity Lotz’s Black Canary was one of the major highlights of Arrow‘s three year run, so I’m thrilled to see her back in the game.
