Batwoman's Arrowverse arrival opened the door to a brand new experience for Arrow star Stephen Amell. During a set visit, he revealed he got to do something he'd never done before during the three-show crossover "Elseworlds": film the show in a location other than Vancouver.
Asked how he felt about Batwoman's arrival, Amell said, "Fantastic. It was great. The idea that we get to go to Gotham City is really exciting, and we got to do something that I’ve never done. I’ve never shot the show anywhere but Vancouver, so we go to Chicago and do all that felt amazing. Ruby’s fantastic, I think she’s going to do great. I’m all for expanding the universe, right? Every time. Always. There’s no scenario whereby I go, 'No, thank you.' I definitely got to shoot on sets both in Gotham City and Star City and Central City and Earth-38 and somewhere that I can’t even properly explain that I just never thought that that would have happened."
During "Elseworlds," Oliver Queen and Barry Allen will swap lives. Thanks to Arkham Asylum doctor John Deegan, who was granted the power to rewrite reality by crossover villain The Monitor, Oliver is the Flash and Barry is the Green Arrow, and their respective teams are completely unaware of the switch. As such, they'll journey to Supergirl's Earth for help, where they'll meet not only her but also Lois Lane and the Man of Steel himself. Batwoman will arrive in "Part 2," which will air in the Arrow slot on Monday.
This year's Arrowverse crossover event will involve the casts of Supergirl, Arrow and The Flash. The event will unfold over three nights, starting with a special episode of The Flash on Sunday December 9 at 8 pm ET/PT. Then, it continues Monday, December 10, with Arrow, and concludes on Tuesday, December 11, with Supergirl.
