THE EPIC FOUR-WAY CROSSOVER WITH “ARROW,” “SUPERGIRL,” “THE FLASH” AND “DC’S LEGENDS OF TOMORROW” CONCLUDES
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 (guest star Chyler Leigh) to take on their most formidable villains yet. Earth’s mightiest heroes – Green Arrow (guest star Stephen Amell), Supergirl (guest star Melissa Benoist), The Flash (guest star Grant Gustin) and White Canary (Caity Lotz) – lead their teams into battle to save the world.
DC’s Legends of Tomorrow, when heroes alone are not enough… the world needs legends. Having seen the future, one he will desperately try to prevent from happening, time-traveling rogue Rip Hunter is tasked with assembling a disparate group of both heroes and villains to confront an unstoppable threat — one in which not only is the planet at stake, but all of time itself.
Based on the characters from DC Comics, DC’S LEGENDS OF TOMORROW is from Bonanza Productions Inc. in association with Berlanti Productions and Warner Bros. Television, with executive producers Greg Berlanti, Marc Guggenheim, Andrew Kreisberg and Sarah Schechter.
