First look as Micheal Keaton's return as Batman in trailer for The Flash

Fans have been given their first look at Michael Keaton as Batman in the new trailer for The Flash.

The teaser for the upcoming DC film dropped ahead of the Super Bowl and people have gone wild on social media.

While the film focuses on Ezra Miller's superhero character, Keaton stole the show for many as we got to see him all suited up again.

The last time he played the Caped Crusader was in 1992's Batman Returns.

Not only do we get to see him in the iconic suit again, but in the trailer he utters those legendary lines of 'I'm Batman'.

One person wrote: "THIS ACTUALLY LOOKS FIRE????!"

Another added: "The trailer had no reason to go that hard."

A third said: "He's baaaaack."

The synopsis for the film has been kept under wraps for quite some time, but we knew there was going to have some element of DC's multiverse involved.

That was confirmed when Ben Affleck and Michael Keaton revealed they would both be starring as Batman in the film.

We now have a much better idea of where the movie is going now that the trailer has dropped.

The synopsis has been update to say: "Barry Allen / The Flash (Ezra Miller) travels back in time to prevent his mother's murder, which traps him in an alternate reality without metahumans.

"He enlists the help of Batman and the Kryptonian castaway Supergirl from alternate realities in order to save this world from the restored General Zod and return to his universe."

DC co-boss James Gunn has high hopes for the movie and even reckons it could be one of the best superhero titles ever made.

Variety reported that during a presentation on the Warner Bros. lot, the filmmaker had some words of praise for the DC movie that has copped a lot of heat amid Ezra Miller’s recent behaviour.

Despite this, Gunn's co-head at DC, Peter Safran, said they are very open to continuing working with Miller.

“Ezra is completely committed to their recovery,” Safran said.

“And we are fully supportive of that journey that they’re on right now. When the time is right, when they feel like they’re ready to have the discussion, we’ll all figure out what the best path forward is.

“But right now, they are completely focused on their recovery.

"And in our conversations with them over the last couple of months, it feels like they’re making enormous progress.”
