The CW crossovers that link the characters and shows from the Arrowverse continues this year with Crisis On Earth-X. Like previous years, the crossover will take place across all DC/CW shows such as Supergirl, Arrow, The Flash and Legends of Tomorrow beginning 27 November 2017.
The epic four-way crossover with Arrow, Supergirl, The Flash and DC’s Legends of Tomorrow begins with a wedding of all things.
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.
