Supergirl director Craig Gillespie recalls "debating stuff" with DC boss James Gunn during the upcoming superhero movie's four-day editing session.
Despite their clashes, though, the filmmaker insisted in a set report from Empire that "it was great to have more of a director than a studio head" to bounce ideas off in post-production. "You can just roll the sleeves up and have a healthy debate," he explained to the magazine. "It would get into the tiniest things... music choices... that sort of push and pull."
