In the ‘The Flash’ trailer, Michael Keaton return his role as Batman.

The Flash, from DC, has been one of the most eagerly anticipated superhero projects, especially when co-CEO James Gunn stated that it would play a critical role in rejuvenating the entire cinematic universe. The freshly released teaser has raised the stakes even higher, with Ezra Miller playing two versions of Barry Allen who meet in a universe where several realities collide.Michael Keaton’s (re)appearance as the caped crusader packs the strongest blow, recreating his role from Tim Burton’s flicks and even saying the classic line, ‘I’m Batman!’ Michael Shannon reprises his role as General Zod from Man of Steel, adding to the nostalgia factor. Overall, the teaser has plenty of ‘Ooh’ moments to keep us excited for the film’s June 16 release.
