Scarlett Johansson is a serious person, says Vogue in a traditional fawning profile. She has thoughts! She has feelings! She's not just a pretty face. Just ask Stella McCartney. "We started sipping dirty martinis with some friends of hers," McCartney says, "and she opened a debate, which was 'Are you born a killer, or are you made into a killer?' I thought, Wow, she’s not just a pretty blonde actor." Johansson is so wonderful, in fact, that she even sang "Rocky Raccoon" once at an open mike with the Avengers cast — while in Ohio. World's bravest human?
