Next month, Supergirl, The Flash, Arrow, and Legends of Tomorrow will all be part of a massive four night crossover which assembles pretty much every character from each respective series. Things will kick off in the final scene of the November 28th instalment of Supergirl according to Entertainment Weekly, and while they promise to reveal more this week, they have shared a few intriguing details.
For example, they got to visit the set of the crossover, and while there, the magazine got to see a lot of very cool stuff, including: "Supergirl fly, The Flash and Cisco tear a hole in the fabric of space-time (or pretend to), and even saw someone get shot. No, we can’t tell you who, but we can tell you the threat that set the sprawling plot in motion: The Dominators, mind-controlling extraterrestrials threatened by Earth’s surging population of metahumans. If you’re wondering if "mind-control" = "we’re totally going to see these superheroes fight each other," then you’re absolutely [REDACTED]."
When we'll get our first look at the crossover remains to be seen, but for now, the cover shows off Green Arrow, The Flash, and Supergirl together for the first time. It's a pretty damn cool sight, eh?
