New The Flash footage was shown at CinemaCon, and it’s promising a lot of callbacks.
Please note that the following information can be considered spoilers at this point. Read past this point at your own risk.
ComicBook.com provided a description of the footage.
“Barry Allen fidgets in a line. He’s at work. Flash travels back outside his childhood home. In his childhood room, Blue lightning flickers around Barry. He looks at photos of his mom and dad and kid Barry. ‘Time has a pattern. It can help deliver certain events to certain people… drawn to each other like magnets… ‘ At Wayne manor, we see someone with shoulder length white hair from behind. He opens a secret door to reveal seven Batsuits stood together. Elsewhere, Flash slows down time and races up the side of a building. Batfleck rides a Bat bike in a car chase with police – it’s daytime. An unmasked Keaton is dressed as Batman, and says ‘You want to get nuts? Let’s get nuts.’ He says this to Barry, alternate Barry, and Supergirl. Title card: THE FLASH. Keaton has an upgraded version of the 89 Batsuit with a bold yellow emblem.”
Not included in this description, but documented in several other reports, there appears to have been a quick flash of Michael Shannon as General Zod. This has been rumored for some time now, and it appears to have now been confirmed.
No word as of yet when or if this reel will be released to the public.
The Flash will hit theaters on June 23, 2023.
