In a recent interview with IGN, Grant Gustin, star of The Flash, talked about a potential crossover between The Flash and the upcoming CBS’ series Supergirl:
“Supergirl, yeah,” Gustin said. “It also is exhausting to think about. But, if they’re like, “Hey we’re doing Supergirl now and we want the Flash to be on a Supergirl episode,” I’m going to get excited about that and then after that worry about how we’re going to make it work. But yeah, of course! I’m down. I’m down for any type of cool crossover as long as we can make it work.”
The Flash returns on Tuesday at 9 p.m. ET on The CW.
