Warner CEO Jeff Bewkes Says DC Films Have Room for Improvement This has been a rocky year for DC Films, with Batman v Superman: Dawn of Justice underperforming against expectations (though still earning $873 million worldwide) and tanking with critics, Seth Grahame-Smith having been replaced by Rick Famuyiwa as The Flash director, Ben Affleck taking on an executive producer role on Warner Bros.‘ upcoming Justice League, producer Chuck Roven’s involvement being diminished, and executive VP Jon Berg and DC CCO Geoff Johns taking the reigns of co-running the DC Films banner.
