DC’s The Flash movie is said to get another Barry Allen, with Grant Gustin having a cameo in the already stacked film.

DC's upcoming Flash movie is said to feature a cameo of Grant Gustin, the star of the CW Arrowverse series of the same name. Directed by Andy Muschietti, the long-awaited Barry Allen solo film is finally kicking in high gear after many years of being stuck in the development stages. Filming has finally begun on The Flash, which is set to modify the Flashpoint Comics arc, breaking the DCEU's Multiverse wide open in the process.

The Flash already has some exciting supporting roles - Sasha Calle will make her debut as DCEU’s Supergirl. Kiersey Clemons will reprise Iris West's role after briefly appearing in Zack Snyder's Justice League. Ben Affleck and Michael Keaton will both be shown as their respective Batmans to help Barry Allen make the time travel mess he makes. It is unclear as to how many of them will be featured in the film, but if the latest news is any indication, it could be in another multiversal superhero team-up in the store.
