Scarlett's 'Island' Getaway

The 20-year-old but incredibly sophisticated Johansson was somewhat of a surprise for [director Michael] Bay, especially when it came to her sex scene with McGregor.

"How many times I have had to say [to an actress in her dressing room], 'Come on, come out. You look beautiful,'" he says. "I get the call from the assistant director. 'She needs to see you.' And I'm like, 'Oh, god. Here we go.' I'm ready to do her love scene and she's not going to come out. I knock on the trailer of her door. 'Scarlett?' 'Yes?' 'Can I come in?' The door opens and she goes, 'I'm not [expletive] wearing this bra! This cheap-ass bra! OK? I'm going naked.' And I say, 'Scarlett, you can't go naked. The movie has to be PG-13!'"
