The CW has had a lot of success with their superhero shows "Arrow" and "The Flash." During the Television Critics Association's winter press tour, the network announced that it was renewing both shows. The CW is also expecting "iZombie" to bring in good ratings.

According to The Hollywood Reporter, the network wants to continue with its winning streak and is considering developing another "Arrow" spinoff. CW President Mark Pedowitz said at the event that there has been talk of expanding the "Arrow" and "The Flash" universe.

Greg Berlanti, executive producer of "Arrow," added that the potential spinoff could be based on the comic book character Atom (aka Ray Palmer), played by Brandon Routh on the series. In the comic books, Atom can shrink to a subatomic size, and one of the first times the character has been seen in a live-action format was on "Arrow."

"We're in very early talks in a very general idea that we haven't gone deeper on yet," Berlanti said at the event.

Routh chimed in that he was willing to continue playing the role.

"When [the 'Arrow' role] was proposed, I was hesitant to step into DC world again," Routh said, who played Superman in 2006's "Superman Returns."

"We just love this universe and we want to keep growing it," Berlanti told The Hollywood Reporter. "We are trying to do more of what we enjoy, and it's true: the shows are so plentiful with characters and storylines. There's a region of the universe that we felt like we haven't dealt with yet that we'd like to deal with."
