Earlier this month a fan asked the very active facebooker and Arrow star Stephen Amell about a listing that had been thrown up on IMDB listing Bruce Wayne's appearance in an upcoming episode, to which Amell quickly shot down.
But, on a recent edition of the Quiver Podcast, Amell was asked about the topic again and responded about how much he would like the movie world of DC and the tv-world to be able to cross over.
Of course...I would like them to have a shared universe...We are trying to put them on a level where if Warner Brothers and DC Comics decided they wanted to them to be a part of the movie, people would buy it
I think that the characters we are creating in our universe can stand next to Henry Cavill and Ben Affleck and Gal Gadot.
If I had a number one…well, if I had a number one it would be Batman, of course, because they would hate each other.
It would be amazing because so many people have always said that Green Arrow was like a rip-off of Batman. I would just love some piece of dialogue where I’m learning about Bruce Wayne, and I learn that he’s a billionaire and that he runs this company and that he’s a vigilante at night trying to clean up the streets of Gotham.
And I would love to just go, ‘Think of something original, Bruce.’ That would be amazing, but who knows.
So far, even with a very strong tv show in Arrow to work with, DC/WB has shown little interest in crossing over the two universes. Early rumors seemed to indicate that DC may use the the same actors that play Nightwing and Flash in upcoming Arrow episodes if they proved to be hits with the fans, but that may simply have been wishful thinking.
Here's the entire podcast, the DCU talk begins around 15:30:
