Elseworlds: How Arrow's Stephen Amell Channeled His 'Inner Barry Allen'

The Arrowverse is having its first Freaky Friday moment. In "Elseworlds," the upcoming three-show crossover, Barry Allen and Oliver Queen will swap lives. During a set visit, Arrow star Stephen Amell weighed in on what it was like to trade places with The Flash's Grant Gustin for a few episodes.

"It was the most fun that I’ve had maybe ever throughout the course of doing the show," Amell shared. "Grant [Gustin] and I had a discussion very early on, and Grant and I saw each other at dinner last night because The CW executives were up here for the Flash 100th episode party and the Supernatural 500th episode party, and it was weird because Grant and I, after spending every waking minute with each other for the better part of a month, we hadn’t seen each other in like 10 days. It was like, 'How are you?'"

"I had so much fun, but we had a discussion very early on that if this was going to work, that we really had to go for it, right?" he continued. "So there are elements of because he has my learned abilities, and I have his superpowers, there are elements of each other’s personality that each of us have to embrace in order to be successful at the mission that’s in front of us. So every once in a while, I’m channeling my inner Barry Allen, and I’m looking at Grant after the take going, 'Is it too much?'"

"But no, we had a blast. I think that the crossovers this year, even if we don’t have as many DC characters necessarily as we did last year, this feels like the first time or at the very least the best example of us just embracing the fun of it all and embracing all of the opportunities that we have because of all of the things that we’ve had a chance to do over the years," he concluded.

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.

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.
