A whole host of images have been released, notably a huge group photo including heroes from ArrowThe FlashSupergirl, and Legends of Tomorrow coming together. Another photo sees Dark Arrow, Overgirl, and Reverse Flash stand together -- they're the evil equivalent to the heroes we all know and love, but from a world where Nazis rule.

This year’s crossover aims to be more like a movie than a four-part special. “When we first did the crossover, I guess back in our third season and The Flash’s first season, it was very much like ‘It’s an episode of The Flash where I show up, and then an episode of Arrow where he shows up,’” Arrow star Stephen Amell said recently. “And even last year, it was like ‘You know, Flash showed up on Supergirl, and then it was an episode of The Flash, an episode of Arrow and an episode of Legends.’ But this year is just a four-hour movie.”

Last year’s Arrowverse crossover, “Invasion!”, brought together the stars of Arrow, The Flash, Legends of Tomorrow and Supergirl for a story inspired by the 1988 DC Comics event of the same name.

This year’s four-part crossover will air across two nights, beginning Monday, Nov. 27 with Supergirl and Arrow (on a special night for one week only) and concluding Tuesday, Nov. 28 with The Flash and Legends of Tomorrow.
