Grant Gustin & Stephen Amell Film Scenes With Ciara Renee For New 'Flash/Arrow' Crossover

Grant Gustin meets up with Stephen Amell on the set of The Flash and Arrow in Vancouver, Canada on Friday afternoon (October 30).

“My last scene on the #Flash / #Arrow crossover ended like I thought it would: With me & @grantgust spooning,” Stephen, 35, joked on Twitter after they wrapped.

The two filmed new scenes with Ciara Renee, who will star as Hawkgirl in the upcoming DC’s Legends of Tomorrow.

Later that day, Grant got on his costume for Halloween — and it was The Flash!

“Got to shoot a one on one scene with @cavanaghtom today for the first time in a while. Called for a photo,” Grant captioned.

Tom Cavanagh came back with another one: “#Cutbacks.”
