Arrowverse Elseworlds: Grant Gustin and Stephen Amell reveal some superhero body swap details

After being teased with a sneak peek of Oliver Queen waking up in Barry Allen's apartment and living Barry Allen's life earlier this week, we finally have some details on what exactly the annual Arrowverse crossover event will be about.

The Flash star Grant Gustin and Arrow star Stephen Amell spoke to Entertainment Weekly about this year's crossover, titled ElseworldsApparently, things will start off with Arkham Asylum employee John Deegan rewriting reality. This results in Oliver suddenly waking up to Barry's life, while Barry will exist as Oliver — with them being the only two who realize that things are askew.

"You’re not going to see me playing Oliver Queen’s mannerisms, or Stephen playing Barry’s mannerisms," explained Gustin. "It’s more being aware that for some reason we’ve switched lives and destinies. It’s more the fun of the situational comedy that we keep finding ourselves in, and less us having a complete role reversal. We get to see Stephen do some of the more goofy speed stuff I have to do on a regular basis, and I get some actual combat as Green Arrow. So we just see different colors for each of us."

This not only answers what exactly was going on in that clip, but also sheds some light on last month's poster, which had the Flash and Arrow wearing each other's costumes. It turns out it's more than a simple wardrobe change. It turns out the two characters will also be swapping superpowers, as Amell revealed. 

"Having superpowers is crazy! Wearing the Flash suit is crazy! The idea is that in order to be the best version of Barry Allen, which I have to be because we face a threat, there are elements of his personality I have to embrace, and there are elements of my personality that he has to embrace."

In addition to this superhero body swap, Elseworlds will also introduce Tyler Hoechlin's black-suited Superman, Elizabeth Tulloch's Lois Lane, and, of course, Ruby Rose as Batwoman. And, in all likelihood, a few other surprises as well.

Elseworlds' three-night event will kick off Sunday, Dec. 9, on The CW.
