"Arrow" executive producers Marc Guggenheim and Andrew Kreisberg have hinted that the comic book heroes from the 'Birds of Prey' may make an appearance in the upcoming second season. Speaking with TV Guide, Guggenheim says:
"We have an idea for how to do our version of Birds of Prey. When you think about it, we have a lot of pieces. It's a lot like the Suicide Squad.
As we continue to populate our world with new characters and some returning people from last year, you start to go, "We're really close to that!" We saw this awesome bit of production art for a new set that we realized plays into Birds of Prey completely. Our Art Department wasn't even intending that!
There's certainly a momentum towards that, but everything has to happen in due time. With respect to Birds of Prey specifically, there's an actress that we particularly need to make that piece work and we need to check on her availability."
In the comics, the 'Birds of Prey' began with a partnership between Oracle (Barbara Gordon) and Black Canary (Dinah Lance) while Huntress (Helena Bertinelli) frequently figures into the story.
Huntress already appeared in the first season of "Arrow", while Black Canary has been seen in the trailers for the second season and will play a recurring role. Guggenheim is likely referring to locking down an actress to play the wheelchair bound Barbara 'Oracle' Gordon.
