From the moment that it had been announced, this year’s Arrowverse crossover (“Crisis on Earth-X”) had promised to be a huge one, and the storyline’s synopsis makes it seem like an even bigger event.
The CW releases a different synopsis for every Arrowverse series — Arrow, The Flash, Supergirl and DC’s Legends of Tomorrow, but for the upcoming 4-part event, the network has released a single, longer than the usual synopsis and it covers every chapter of the event.
While much of the synopsis recaps details we know (Barry and Iris are getting married, and while their ceremony is unfolding, nazi-esque villains from another dimension arrive and attack the heroes), it reveals a few key information. Wentworth Miller is back, but not as Captain Cold; rather, he will play Citizen Cold, a heroic version of Leonard Snart from another reality. And, it seems that he will be teammates with The Ray, a new hero that has yet to be introduced on the live-action Arrowverse series.
“THE EPIC FOUR-WAY CROSSOVER WITH “ARROW,” “SUPERGIRL,” “THE FLASH” AND “DC’S LEGENDS OF TOMORROW” BEGINS — 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. Larry Teng directed the episode with story by Andrew Kreisberg & Marc Guggenheim and teleplay by Robert Rovner & Jessica Queller (#308). Original airdate 11/27/2017.”
This year’s 4-part Arrowverse crossover is set to air on The Cw across 2 nights, beginning Monday, Nov. 27, with Supergirl and Arrow (on a special night for a week), and concluding Tuesday, Nov. 28 with The Flash and DC’s Legends of Tomorrow.
