Ben Affleck’s Batman Is Back in New ‘Flash’ Set Photos Thus far, The Flash director Andy Muschietti has used his Instagram to tease the film’s costumes for the title character, Supergirl, and Michael Keaton’s Batman. But The Flash also features an additional Dark Knight: Ben Affleck’s Batfleck, and so far we haven’t gotten any sorts of teases of what his new Bat-suit will look like. We still don’t have an official look at the new Batfleck yet, but there’s now a whole batch of set photos that show off Affleck’s Batman (or a stuntman’s closest approximation) driving around in a brand-new costume and Bat-cycle. You can see what’s popped up on Twitter so far below:
