To get a shot at directing his remake of “A Star is Born,” Bradley Cooper passed on an upfront payday in exchange for a piece of the profit. And that gamble paid off. But as Cooper is painfully aware, the movie business has changed. “Those days are completely gone,” Cooper says. “So, there is trepidation I have with that, no question. And I have thought: I really have to actively start thinking about other ways of making revenue that have maybe nothing to do with movie making.” In part two of KCRW’s interview with Bradley Cooper, he shares his worries about the streaming future. He also remembers picking up filmmaking tips on the set of “Alias.” And he shares how he created the memorable voice of Marvel’s Rocket Raccoon.
