Supergirl's Alex Details Role in Arrowverse Crossover Crisis on Earth-X

Alex Danvers Supergirl

Alex Danvers will make the jump to Earth-1 for Barry and Iris' wedding in the Arrowverse crossover "Crisis on Earth-X." Unfortunately, her trip won't go quite as smoothly as expected when villains from Earth-X crash the party. During a set visit, Alex actor Chyler Leigh discussed her involvement in the four-show crossover, the other Arrowverse characters she got to meet, the atmosphere on set and more.

"Oh, I'm all over it! Every day, 14-hour camera days, every single day for three and a half weeks. Yes, I was there every day," she revealed.

"We were the only two [from Supergirl] really that went over in the crossover. It was just primarily the both of us," she explained. "Went there for Barry and Iris' wedding. That was whole point for going there, the catalyst behind it. It's comic book that nothing is ever peachy and easy. Disaster ensues. It's everybody banding together and figuring out strengths, weaknesses. You have all these minds in one place, and all these superpowers in one place, all these costumes in one place. I was like, 'I'm really glad that I have a DEO outfit. Like I'm super stoked about this.'"

"You have all of this in one area... Actually, we joked a lot about it because there are a few scenes where you see everybody together. It looked like a high school reunion, where it's like we're all standing, just like, 'This is really funny. What do we do for a living?'" she added with a laugh.

"With Alex and Kara, it is very much a duke-it-out, like, 'We're here together. We're in this.' At certain moments, we're fighting for each other, fighting to get to each other and fighting together," she teased. "You really get to see a lot of sides of everybody, and sides that you wouldn't expect."

"It was a lot of fun. It was a lot of work and exhausting, but it was a lot of fun," she shared. "We all had a really great time together. The biggest thing about it is that when you're working that much, and you're working that hard, and you have such little time, it's basically making like a huge feature in three weeks, and so, it was ridiculous. But you put it all together, and you just go, 'Wow.' What we accomplished, I'm very proud of. I'm really curious to see it what it looks like all put together. There were days where we would shoot on three shows in one day and just shuttle between, and it's like, 'I don't remember anybody's name.' This is my first crossover, so I didn't know anybody."

"But at the same time, you start to see people working up in Vancouver that I worked with 10 years ago," she continued. "Crew members just kind of going high-fives, walking around, saying, 'Hey, how's it going? This is great!' All around, it was a great experience. We all knew that we were in the thick of it together. Everybody kept as highest spirits as you can when you're tired. But we all just had fun and laughed as much as we could and just enjoyed the experience, because how could you not?"

Leigh also offered a hint about who Alex gets to interact with in the crossover. "A lot of the moments that she had are with Oliver and Barry and Sara and a lot of the Legends cast," she said. "That was a big part of that duo, everybody there. That was kind of the biggest part of it."

This year’s four-part crossover will air across two nights, beginning Monday, November 27, with Supergirl and Arrow (on a special night for one week only), and concluding Tuesday, November 28, with The Flash and Legends of Tomorrow.
