RELATED: The CW’s Crisis on Earth-X Trailer is Here!

The new event begins with Supergirl on Monday, November 27 during its usual 8 PM time slot, with Arrow following at 9 PM. Those episodes will be followed by The Flash and DC’s Legends of Tomorrow on Tuesday, November 28 at 8 PM ET and 9 PM ET, respectively.

The crossover event is described as follows: Barry (guest star Grant Gustin) and Iris’s (guest star Candice Patton) wedding brings the gang together, but things go awry when villains from Earth-X attack the ceremony. All of the superheroes band together with help from their super friends like Citizen Cold (guest star Wentworth Miller), The Ray (guest star Russell Tovey), Felicity Smoak (guest star Emily Bett Rickards), Iris West and Alex Danvers (Chyler Leigh) to take on their most formidable villains yet. Earth’s mightiest heroes – Green Arrow (guest star Stephen Amell), Supergirl (Melissa Benoist), The Flash (guest star Grant Gustin) and White Canary (guest star Caity Lotz) – lead their teams into battle to save the world.

Executive producers Andrew Kreisberg & Marc Guggenheim penned the story for the crossover with the individual parts directed by Larry Teng, James Bamford, Dermott Downs, and Gregory Smith.

Heroes and villains face-off in the 2-night crossover event, #CrisisOnEarthX, starting Monday at 8/7c on The CW. http://pic.twitter.com/Gi6skG9NlS
