Bardot, Deneuve...Sagnier? France's latest bombshell export, 24, dives into her first English-language film by taking it all off as a sexually provocative teen in the thriller Swimming Pool. Her first reaction to getting the part?" 'Oh my God, I have to diet,' " she says. "I'm okay [looking]. But you want a sex bomb!"
Growing up in the Paris suburbs, Sagnier began acting at 8. Still, she was intimidated by her famous costars in last year's 8 Women: "Every time Catherine Deneuve would speak to me, I'd cry." Sagnier, an avid hiker and sailor, next plays Tinker Bell in a big-screen Peter Pan, due in December. "I'm not in a hurry," she says of her career. "I don't have the aim of owning four villas. I have everything I need."
