Ever since Ben Affleck was chosen to be the Dark Knight in the upcoming Batman v Superman: Dawn of Justice film, DC fans have been in an uproar. Things have died down since, but there are still a selected few who believe Warner Bros. should have gone with another actor, namely Josh Brolin.
It has been long rumored that Josh Brolin was Zack Snyder's first choice, but as it stands, it appears Warner Bros. had no interest in signing Brolin, as the studio had already settled on Ben Affleck even before giving the actor the heads up.
Batman v Superman: Dawn of Justice producer, Charles Roven, has cleared the air in an interview with Hollywood Reporter. According to Roven, Warner Bros. was more interested in an actor that is mature and with a huge physicality. The studio wanted a Batman that is taller than Superman, and only Ben Affleck fitted the script.
