Ezra Miller was originally casted for the flash in the DCU. Recently however, Ezra has committed crimes such as public intoxication, Alleged grooming of a minor under 18, and much more. It is rumored that the DCU has expressed interest in Dylan O’Brien, however, fans of the popular television series ‘The Flash’ (Starring Grant Gustin as Barry Allen/Flash) disagree, and think Grant deserves the role for his commitment and dedication to the DCU.
