EW.com has our first official look at Supergirl teaming up with The Flash, Arrow, and John Wesley Shipp also as The Flash.
The three-night event begins with Arkham Asylum doc John Deegan (Lost’s Jeremy Davies) rewriting reality, which results in Oliver (Amell) and Barry (Gustin) swapping lives. In this new reality, Oliver Queen looks like Gustin and Barry Allen looks like Amell, and the two heroes are the only ones who know they’re in the wrong lives and have each other’s powers. This not only explains what’s going on in the recent promos, but also why the actors have swapped costumes.
Supergirl co-showrunner Robert Rovner said, “She’s trying to help them navigate what they’re going through and support them and kind of battle their way back to being who they’re supposed to be.”
The special 3-night “Elseworlds” crossover event will begin in “The Flash” on Sunday, December 9 at 8.00pm ET, and then continue in “Arrow” on Monday, December 10 at 8.00pm ET, and will conclude with “Supergirl” on Tuesday, December 11 at 8.00pm ET.
