"Crisis on Earth-X" Continues In New Arrowverse Promo

The CW has released a new promo for the second night of "Crisis on Earth-X", this year's four-show Arrowverse crossover.

The episodes of The Flash and Legends of Tomorrow will serve as an epic conclusion to the event, which began in tonight's episodes of Supergirl and Arrow. The crossover event sees the Arrowverse's heroes sucked into a conflict with the villains of Earth-X, after they halt the wedding of Barry Allen/The Flash (Grant Gustin) and Iris West (Candice Patton).

But as it turns out, the villains of Earth-X are after something more - the heart of Kara Danvers/Supergirl (Melissa Benoist), which will help save her evil doppleganger Overgirl. And seeing as night one ended with the Arrowverse's heroes getting captured and brought to Earth-X, it appears the fight is just getting started.

The promo also gives a look at some of the characters that will be introduced in Parts 3 and 4, including Ray Terrill/The Ray (Russell Tovey), Leonard Snart/Citizen Cold (Wentworth Miller), and an Earth-X version of Arrow's Quentin Lance (Paul Blackthorne).

While it's uncertain exactly how the Arrowverse's heroes will make their way out of this, it sounds like viewers will be taken on one hell of a ride to get there.

"It really is, for the first time, it's an event," Stephen Amell, who plays Oliver Queen/Green Arrow, recently told reporters. "It's not a crossover anymore. Call it the crossover if you want. But it's kind of like calling the Super Bowl just a football game. Yeah, sure, they play football, but there's so much other stuff that goes on with it. It's an event."

"Crisis on Earth-X" is a four-hour event that will air on November 27th and 28th beginning at 8 p.m. and running for two hours each day; Supergirl (8 p.m. Monday), The Flash (8 p.m. Tuesday) and Legends of Tomorrow (9 p.m. Tuesday) will remain in their normal time slots but Arrow will move from Thursday to a 9 p.m. Monday placement for the week.
