Leonardo DiCaprio

Julie Delpy

The actress — who was nominated for a best adapted screenplay Oscar along with co-star Ethan Hawke and director Richard Linklater — went topless for Before Midnight, the third film in a trilogy. Of her decision to do so, she told GQ magazine: "I wanted it to be realistic! Sometimes I see films where people have sex with a bra on. I mean, what country do they come from? I don't think I've ever had sex with a bra on in my life, except maybe once. It's not the most comfortable thing to be acting topless. I've never actually showed my body that much, even though I'm a French actress. It was a big deal for me to do it. This movie isn't fantasy. This is a film for people who can handle a pair of tits."

Colin Firth

For Colin Firth's role in A Single Man, in which the actor plays an English professor unable to cope with the sudden death of his partner, Firth stripped down and was nominated for Best Actor at the 2010 Academy Awards.
