'Arrow' Season 3 Spoilers: Cast Tease Show Crossover With 'Constantine,' 'Supergirl' and 'Gotham'

Lead cast member of the hit crime-fighting TV series "Arrow" Season 3, Stephen Amell, recently spoke at the Dallas Comic Con's Fans Days this weekend.

During the event, the Oliver Queen actor teased the fans that more DC Comics characters are heading towards the CW series. To amped up the excitement, the 33-year-old Canadian actor reveals possibility of a huge crossover with various other DC TV-adapted shows like "Constantine," "Supergirl," and perhaps the Batman spin-off "Gotham."

"It would be interesting. I was saying this earlier. It would be interesting to cross over with Constantine, only because he knows a lot about the Lazarus Pit, which is something that we've introduced in the show this year," Amell said.

"It would be cool to crossover with Supergirl because it's something with Greg Berlanti, who's the helmer and sort of the brain trust or the center of the brain trust of Arrow and The Flash and I know so many of the people that are involved in the production of that show so that would be really interesting," he went on to say.

The actor meanwhile admits the challenges the crew has to face when they opt to cross over with the Dark Knight-less "Gotham."

"And Gotham would be a tough one, just because I think they're out in a different time but the crossover with The Flash was so much fun and did so well that I can't imagine a world -- a universe, no pun intended -- where that didn't happen and continue to happen all the time," Amell said further.
