After being first introduced on Arrow, The Flash pilot is set to feature an appearance from Mr.Queen/Arrow himself.
Arrow won't be visiting Barry's hometown of Central City though, "In the Flash pilot, Barry comes to me," Amell told TVGuide. "[It's a] little snippet in the Flash pilot where he and I share a scene together, it's in his pilot, but [filming] it felt like our show because he's coming to Starling City. That, to me, was one of the most rewarding things that I did as an actor because it was essentially the same crew that we used for our pilot, and it was two years later and it was the same director. It was like going back in time".
"We'd be insane if we didn't do crossover stuff," Amell added. "I don't know that it has to be an event or big moments, but the shows share a universe, and not utilizing that fact would be insane. I'm sure that we will at some point."
