Stephen Amell Teases 'Arrow' & 'Flash' Crossover Episode!

Cousins Stephen and Robbie Amell are totally swoon-worthy at a special screening for CW shows Arrow and The Flash held at the Crest Theatre on Saturday (November 22) in Westwood, Calif.

Also making appearances at the big screening were The Flash cast members Grant Gustin, Danielle Panabaker, Carlos Valdes and Arrow‘s Audrey Marie Anderson, David Ramsey, and Emily Bett Rickards, along with behind-the-scenes guys Greg Berlanti, Peter Roth and Marc Guggenheim.

“Starling City and Central City are very different places. So when I go to Central City, it’s very much, ‘Alright, I’ll tag along. We’ll do things your way.’ And then the very next night, in our episode, it’s ‘I’m sorry, we’re not in Central City anymore. We’re doing things my way. Things are different here,’” Stephen told Extra about the upcoming crossover episode. “So it’s a really interesting checkpoint for both shows because we’re able to teach these big lessons to the characters.”

The crossover eps air on December 2 and December 3!
