Imogen Poots wears an Isabel Marant tank top; J Brand jeans; her own bracelets.

“I honestly have not seduced any older men,” says the 24-year-old British actress Imogen Poots. “I swear!” Onscreen, though, she’s had more than her share of May-to-December trysts, with the likes of Mark Ivanir in last year’s A Late Quartet and Michael Douglas in 2009’s Solitary Man. Equally adept at drama and comedy, and able to skew younger or older than her years, Poots has a variety of high-profile projects on her docket: a Jimi Hendrix biopic, a Nick Hornby romance, a rom-com with Zac Efron, and even a top-secret Terrence Malick film. “Maybe if I play adults, I can let the rest of my life devolve into childlike behavior,” she says. “I’m not really in a rush to grow up.”
