The trailer for “The Flash” debuted Sunday during the Super Bowl between the Kansas City Chiefs and Philadelphia Eagles.

Ezra Miller is back as The Flash, six months after the actor issued an apology for a string of scandals.

But, the buzz was about Michael Keaton, who makes an appearance as Batman and social media took immediate notice.

Miller previously played the part in 2016′s Batman v. Superman: Dawn of Justice and 2017′s Justice League.

“Worlds collide in The Flash when Barry uses his superpowers to travel back in time in order to change the events of the past. But when his attempt to save his family inadvertently alters the future, Barry becomes trapped in a reality in which General Zod has returned, threatening annihilation,” a press release states.

“Unless Barry can coax a very different Batman out of retirement and rescue an imprisoned Kryptonian… albeit not the one he’s looking for. Ultimately, to save the world that he is in and return to the future that he knows, Barry’s only hope is to race for his life.”

The trailer, which appears to show a time traveling element, teases the returns of Keaton and Ben Affleck as their Batmen.
