Behind the Scenes of ‘The Flash’-‘Supergirl’ Crossover (VIDEO)
“I think the shows really exist well together, and these two characters exist really well together,” Gustin says in the behind-the-scenes video below.
“It just felt like we were literally living a comic book, bringing it to life,” Benoist adds.
While Barry is in National City, he and Kara form a joyous friendship—and he assists her with taking down Siobhan/Silver Banshee (Italia Ricci) and Livewire (Brit Morgan).
Check out the video for more from Benoist and Gustin, as well as Supergirl stars Mehcad Brooks and Jeremy Jordan.
