Natalie Portman Won't Shill for Makeup.

A very serious Natalie Portman promoted her new venture for aspiring filmmakers this week at the Tribeca Film Festival and dropped a huge hint about what she’s not doing in the future. “I don't have a problem with making money, but I don't believe in doing something you don't believe in to make money, like a makeup campaign or something like that—the opportunities that young actors have all the time," she says. The Other Boleyn Girl also mentioned, “It's possible to do something positive in the world that’s still entrepreneurial.” Don’t knock Revlon until you’ve tried it, Nat. Meanwhile, her MakingOf Web site hosts interviews with composers, editors, and those involved in all aspects of the filmmaking industry. A few notable moments: Billy Bob Thornton “shares his insecurities” (although his Canadian radio interview already showcased those) and Arrested Development funnyman Jason Bateman offers advice on nailing auditions.
