‘The Flash’ Star Grant Gustin Teases Barry-Iris Wedding, ‘Crisis On Earth-X’ Crossover

“The Flash” star Grant Gustin revealed that Barry and Iris’ much-anticipated wedding felt a little bit strange for him.

In an interview with Collider, Gustin said that while Barry (Gustin) and Iris’ (Candice Patton) nuptials is “in some ways fitting” to be part of the “Crisis on Earth-X” crossover, the actor admitted that he feels odd that the ceremony doesn’t take place in CW’s “Flash” installment of the four-way crossover.

“It’s a little strange that we’ve been leading up to this wedding and it’s not even on ‘Flash,’ it’s technically on a different show,” the actor said. “I’m interested to see how some viewers feel about that. But [on the other hand] it’s also how this show started, on ‘Arrow.’ We’ve consistently had these crossovers and we’re bringing so many characters together for this wedding, [so] it’s kind of fitting that it happens somewhere else.”

Executive producer Andrew Kreisberg told ComicBook.com last month this year’s crossover is more tonally cohesive than the previous Arrowverse crossovers, so viewers “won’t know what show it is depending on what episode it is.”

“In the past, an ‘Arrow’ episode felt like an ‘Arrow’ episode, a ‘Flash’ episode felt like a ‘Flash’ episode, and ‘Legends’ felt like ‘Legends.’ With this crossover, we’re telling it like a collective story,” executive producer Todd Helbing told Collider last month. “It’s so fun to see them all together, working together and being together for four hours. While we’re progressing the narrative on all four shows, it’s really this amazing through line for everybody.”

As far as the scope of “Crisis on Earth-X,” Gustin said that it’s the biggest crossover they have ever done. “There’s more people than ever included, some of the biggest sequences you’ll see with the most superheroes we’ve ever seen together at any given time,” Gustin told Collider. “Barry and Kara (Melissa Benoist) have a few interactions that are fun, and I meet a couple new characters. It’s bigger than ever before.”

The crossover will air across two nights. It begins with “Supergirl” and “Arrow” on Monday, Nov. 27 at 8 p.m. EST, and ends with “The Flash” and “Legends of Tomorrow” on Tuesday, Nov. 28 at 8 p.m. on The CW.
