A sneak peek trailer at The Flash has given us a first look at the back of Batman's head - Michael Keaton's Batman, that is.
The trailer was shown off during DC FanDome 2021. Ezra Miller appeared on screen and started by saying that they wanted to show off the film, but it was still in production. They then said that they wanted to show off a trailer, but there wasn't enough filmed yet to make one. As disappointing as this seemed at first, they then revealed that a small sneak peek of the film had been put together, which ironically had more in it than the Black Adꩲam footage.
The trailer showcases The Flash as he talks about having the ability to visit any point in time. It seems that he's actually talking to himself at some points, as the trailer showcases two different versions of The Flash, one that more closely resembles the one we saw in the Snyderverse and one that looks a lot younger.
The younger Flash seems to be wearing a spray-painted version of the Batsuit, with Flash's lightning insignia painted over the Bat-symbol. It's possible that he got this in Keaton's Batcave, or it could hint at Affleck's involvement in the film up to that scene. We also get to see our iteration of the Flash and his new outfit. It's much less mechanical than the one we've seen previously and seems to have the speedforce flowing through it. We also got to see the first look at Sasha Calle's Supergirl, although only very briefly.
It's not clear how, but The Flash somehow ends up in what appears to be a very dusty Wayne Mansion. Two versions of The Flash and Supergirl are then approached by Michael Keaton's iteration of Batman, who we don't get to actually see in the trailer unless you count the back of his famously pointy bat-ears.
The trailer then ends with a tease of Keaton's Batmobile, which is hidden underneath some cloth. The audience doesn't get to see it, but we get a hearty "holy shi-" before fading to black.
