Grant Gustin addresses The Flash movie cameo rumors

I was, like everybody probably in the '90s, loved Michael Keaton as Batman and he's back as Batman. And it sounds like they got just about everything else packed into that movie," the actor said in the interview. Gustin reveals that he is curious to see "Keaton back in the suit and how they incorporate it" into the movie.

"No! [laughs] Yeah, there have been a lot of rumors out there for a long time," Gustin said when asked about having a cameo in The Flash. "No one has come out directly and asked me, like ever on the record. People ask me on the street all the time, and yeah, I'm not keeping some big elaborate secret."

Gustin, who has been playing the role of the Scarlet Speedster since 2014, expressed his excitement for the new movie. "As a Flash fan myself, now, I'm just excited to see what they do with it."

The Flash is the longest-running Arrowverse series on CW and easily its best project. The TV show premiered in 2014, just weeks before DC announced that Ezra Miller would be starring in a standalone movie for The Flash. The TV series will be ending its ninth and final season just weeks before the movie hits theaters in June.

The Flash movie will have two versions of the Scarlet Speedster, both played by Miller. The actor will be joined by Sasha Calle as Supergirl, with Keaton and Affleck as different versions of Batman.

The Flash is coming to theaters on June 16 while the TV series ends on May 24.
