With the success of The Flash and Arrow on The CW (the former's premiere was the highest-rated telecast in the network's history) and an ever-increasing number of comic book series on television, fans are wondering when - not if - we'll see the Arrow/Flash universe expand.

Routh as Ray Palmer.

Soon enough, it seems. At today's TCA (Television Critics Association) press tour CW president Mark Pedowitz revealed that they were in very early talks to do an additional spinoff series. The question is: Which character might we see get his or her own show?IGN had the opportunity to sit down with Brandon Routh about his Arrow character Ray Palmer/Atom (stay tuned for more on that) where we asked if he thought they may be leading towards a spinoff featuring his character."With any character you bring on this show that's a possibility, depending on how the fans react and the character is received and developed," the actor reflected. "You know they've shown with The Flash that just being a part of Arrow that it can work. It's exciting. The sky's the limit. DC and The CW have done a great job with the two shows and the platforms in terms being their own entities. What the future holds, who knows? But anything is a possibility."During The Flash/Arrow panel, executive producer Greg Berlanti was asked if an Atom spinoff was something he was actively pursing, to which he said: “We’re in very early talks in a very general way that we haven’t gone deeper on yet."Routh added that he was initially hesitant to return to play another comic book hero after playing - what was to him - the pinnacle of superheroes: Superman in 2006's Superman Returns. The actor was a big fan of Arrow, however, and has had "an amazing experience" on the show. "I'd like to keep playing the character as much as possible," Routh concluded.For now, it looks like Atom is in the lead to get his own show. We will keep you updated as details emerge.Let us know what you think. Would you like to see The Atom get his own series? Is there another Arrow or Flash character you'd like to see in a spinoff series?
