This year's Arrowverse crossover, which brings together Arrow, The Flash, Supergirl, and Legends of Tomorrow, is set to be bigger than any other crossover we've seen before on The CW. Green Arrow himself, Stephen Amell, has gone as far as to call the big event -- titled Crisis On Earth-X -- a "four-hour movie."
Talking on a panel at Salt Lake Comic Con, Amell discussed the four-episode crossover, and teased that it'll really feel like a movie rather than four separate parts of a single story. "Technically it goes Supergirl, Arrow, Flash, and Legends," he explained (via ComicBook). "But you’re not supposed to be watching the Supergirl hour going ‘Okay, this is the Supergirl hour.’ It’s just the first hour of the crossover." This is sure to please fans, especially those who have been pining for a more fluent event to take place.
"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,'" the actor said. "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."
The Arrow actor wouldn't divulge any plot details, though he revealed his reaction to the story after he first read through the scripts. "I can’t spoil it, other than to say that when I read the crossover scripts this year, I felt compelled to email the sort of original [Arrow] team of Greg Berlanti and Andrew Kreisberg and Marc Guggenheim," Amell exclaimed. "And the email just simply said 'Guys, thank you so much for this opportunity, because it’s going to be really, really good.'"
The crossover Amell is talking about is titled Crisis on Earth-X, which sees “all of the heroes in town to celebrate Barry and Iris’s wedding,” when “villains from Earth-X crash the festivities with a deadly agenda.” As seen in a poster for the event, those Earth-X villains are the evil doppelgangers of the Arrowverse’s beloved heroes, who in DC Comics history are from a parallel world in which Germany won World War II.
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.
