Warner Bros. just dropped the final trailer for The Flash, ahead of its release on June 16. The trailer sees Barry Allen (Ezra Miller) trying to fix the multiversal errors caused by his selfish time travel — eventually causing him to seek help from Michael Keaton’s Batman. Ben Affleck's Bruce Wayne is seen warning him of the consequences of messing with time, while Kiersey Clemons reprises her role as romantic interest Iris West, as seen in Zack Snyder’s Justice League.
