During DC FaDome the cast of CW’s The Flash unveiled the trailer for season 7 which you can watch in the player above.
Production on The Flash’s sixth season ended early in mid-March which is why the season’s 19th episode, “Success Is Assured,” became the season finale. However, the show had already started shooting episode 20 when the shutdown happened, and that footage is now being used for season 7.
When The Flash ended, Eva McCulloch/Mirror Mistress (Efrat Dor) had escaped the Mirrorverse and framed Sue Dearbon (Natalie Dreyfuss) for her husband’s murder. Meanwhile, Iris (Candice Patton), who was still trapped in the Mirrorverse, was sent somewhere, and Barry (Grant Gustin) helped Team Flash rally from their recent defeat.
The season 7 teaser reveals the return of season 3’s vertigo-inducing rogue Top (Ashley Rickards), who has an interesting conversation with Cecile (Danielle Nicolet). Meanwhile, Barry desperately tries to build an artificial Speed Force because Eva is “liberating” people and a super-sonic plane is about to crash into Central City. Iris’ neural dissonance has worsened and her broken mind is taunting her with the prospect of never escaping the Mirrorverse.
“Even though it’s only footage really from one episode , pay attention to the way it’s presented. It’s actually huge spoilers all over the place,” said showrunner Eric Wallace about the season 7 teaser.
In addition, Wallace also shared his thoughts on why he wants to use Godspeed as an antagonist in season 7. “I want to make sure new fans — especially young new fans who are reading the comic book right now — are welcomed to the show, so it’s not just Silver Age villains and Bronze Age villains,” said Wallace. “There might be a young girl or a young boy who is reading those Flash comics right now and going, ‘Where’s my villain? My generation’s villain.”
The Flash will return in 2021.
