Every evening, Roven’s office sends him what he calls his night sheet, a to-do list that’s critical to his overseeing projects that can be taking place simultaneously in wildly scattered time zones. "I print it out and carry it with me," he says. "It’s got many more things on it than I can ever accomplish in one day, but at least it gives me something to attack." At the moment, Roven, 65 — who was part of Christopher Nolan’s $2.5 billion-grossing Batman trilogy and David O. Russell’s Oscar-winning American Hustle — is keeping tabs on Warcraft and Batman v. Superman, both in postproduction; Zhang Yimou’s The Great Wall, starring Matt Damon and filming in China; and Warners’ supervillain showdown Suicide Squad, which just began shooting in Toronto. "On the first day, I always try to make sure I’m there for the very first setup," he says, though he freely acknowledges he couldn’t oversee so many major movies "without an incredibly supportive team of producing partners."
