WARNING: This article contains major spoilers for "Into the Void," The Flash Season 6 premiere.
As Barry Allen raced to stop a new meta-human from consuming Central City in a singularity during the Season 6 premiere of The Flash, the Scarlet Speedster briefly left the terrestrial plane as he ran into the black hole. To commemorate the moment, Cisco Ramon eagerly put on Queen's iconic theme song from the cult favorite '80s film Flash Gordon.
For showrunner Eric Wallace, the desire to use the epic theme song was a personal, longstanding ambition, finally fulfilled after working on the Arrowverse series for years.
"I’ve had the idea [to use the Flash Gordon theme] for a couple of years now," explained Wallace in an interview with TVLine. "That line that Cisco says, ‘I’ve been waiting five years!’? Well, I’ve been waiting five years, too, waiting for the perfect moment. And what better than a premiere, in which the Flash essentially gets to go into outer space -- even if it’s just for 10 seconds."
Ultimately, Barry is successful in saving the city once again, having gotten a glimpse of the cosmos as Team Flash prepares for the Arrowverse crossover event "Crisis on Infinite Earths." However, viewers should not put too much hope for the DC television series to license additional Queen music anytime soon.
"I used as much of it as we could," continued Wallace. "If I could afford it, we would have scored the entire episode to Queen music. But that’s a bit out of our budget.”
Airing Tuesdays at 8 p.m. on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanagh, Jesse L. Martin, Danielle Nicolet and Hartley Sawyer.
