Trivia

 * First time that Tom Welling and Erica Durance have played Clark Kent and Lois Lane since the Smallville (2001) series finale eight years earlier.
 * Writers Don Whitehead and Holly Henderson were also staff writers on Smallville (2001). Before filming began, they shared the "Smallville" material with co-creator Alfred Gough.
 * Largely in various animated films and TV series, Kevin Conroy has been playing Bruce Wayne/Batman for more than 20 years, longer than any other actor.
 * Kevin Conroy discussed with Entertainment Weekly how the "Crisis" role took him by surprise, stating how the experience of playing Batman for the first time in live-action "threw him" at first. "I never approached this character from that physicalized aspect. I always just inhabited him with my voice," Conroy said. "When you do that in a recording studio, it's a very intimate experience and you're sort of living in your own imagination. You do it with your eyes closed and you're in this other world, and you have Mark Hamill feeding you [need], and the other actors (because we always recorded together in the booths.)" "To actually be on the set, in the physical world, and to be walking as the character and inhabiting the character in three dimensions, it was a real transition for me," he added. "It did take a while to get used to, I have to admit. I was surprised because I know the character so well."
 * Ruby Rose and Melissa Benoist helped Kevin Conroy overcome this initial obstacle on how to approach his character. "Everybody was so generous to work with. I can't emphasize how enough how welcoming everyone was, especially Ruby. She is so open and giving. I just fell into her eyes at one point and we just connected on camera. It was wonderful," he says, adding that it was "amazing" to work with Benoist, too. "I felt like I was working with old friends I'd known for years. There was just such trust there that I could open up to them on camera."
 * Executive producer Marc Guggenheim spoke of Kevin Conroy, "He is stupendous, He is Bruce Wayne. [It's] just a lot of fun to see this actor who we all mainly know from voice work being on camera. It was really exciting." Conroy's appearance in "Crisis" is the result of a dream. "One of the things that was always on my bucket list is that I wanted to see old Bruce Wayne," says Guggenheim. "We talked about a variety of different casting possibilities, but [Legends of Tomorrow showrunner] Keto Shimizu, who is a huge animated Batman fan, pointed out that Kevin is the right age. We reached out to Kevin and he couldn't have been more lovely and more game for it."
