Born in Scotland 1971, Ewan McGregor has made his mark in both independent (Trainspotting) and big budget (Star Wars prequels) cinema. He has never shied away from shedding his clothes in his films, including full frontal nudity in The Pillow Book and Young Adam.

QUOTE: "I'm doing my bit for the women's movement. The women have always been naked in movies and now I'm just desperate to take my clothes off as much as possible."

After a stint on popular TV show ER, spunky actress Maria Bello moved on to feature films starring in (amongst others) Coyote Ugly (2000), The Cooler (2003) and A History of Violence (2005), the latter two earning her Golden Globe nominations. She has proven to be a fearless and powerful on screen presence in many of her films, and has taken her clothes off in several of them.

QUOTE: "The thing is I don't separate a character's sexuality from what she eats for breakfast. I'm not interested in living that cliché and living in that puritanical nature of things. I don't think that sexuality is something separate. It is like it has become a shadow part of ourselves, which I think is very unfortunate - I myself try to get that shadow out into the light."

On top of being one of cinema's most underrated and hard working actors, Harvey Keitel has also shown fearless ambition in bearing himself in front of the camera, as his two full frontal nude scenes in the disturbing Bad Lieutenant (1992) and The Piano (1993) have shown. After 1995's Ulysses' Gaze, it seems that Keitel has decided to leave his clothes on as he gets on in his years. Most would say it is for the best.

FILMS IN WHICH HE/SHE HAVE APPEARED NAKED: Whose That Knocking at My Door? (1967), Mean Streets (1973), Fingers (1978), The Men's Club (1986), Bad Lieutenant (1992), The Piano (1993), Ulysses' Gaze (1995)

QUOTE: "An actor doesn't do nude scenes. An actor plays an event and tells a story."

Perhaps the greatest actress working in cinema today, Kate Winslet has never been afraid to expose herself emotionally or physically on camera. Her most famous nude moment has to be in the box office smash Titanic where she disrobed in front of Leonardo Di Caprio for an intimate portrait, which was actually drawn by director James Cameron. (Geez, I wonder if he put that in her contract?)

QUOTE: "I like exposing myself. There's not an awful lot that embarrasses me. I'm the kind of actress that absolutely believes in exposing myself."

Oscar winning actress Dame Helen Mirren has appeared nude in a dozen or so feature films. Thankfully, The Queen is not one of them. However, one film that is on the list is the infamous 1979 historical romp Caligola, which generated a huge amount of controversy upon its release due to its hardcore sex scenes (which do not feature Mirren).

FILMS IN WHICH HE/SHE HAVE APPEARED NAKED: Age of Consent (1969), Savage Messiah (1972), Caligola (1979), Hussy (1980), Cal (1984), Cause celebre (1987), Pascali's Island (1988), The Cook, The Thief, His Wife and Her Lover (1989), Prince of Jutland (1994), The Passion of Ayn Rand (1999), Calendar Girls (2003), The Roman Spring of Mrs. Stone (2003), Shadowboxer (2005)

QUOTE: "Flesh sells. People don't want to see pictures of churches. They want to see naked bodies."

After years of taking her clothes off in front of the camera, Diane Lane finally snagged an Oscar nomination for doing just that in the confronting erotic drama Unfaithful. The daughter of Playboy centrefold Colleen Farrington, Lane seems to have inherited her mothers taste for taking her clothes off.

FILMS IN WHICH HE/SHE HAVE APPEARED NAKED: Ladies and Gentlemen The Fabulous Stains (1981), The Cotton Club (1984), Lady Beware (1987), The Big Town (1987), Vital Signs (1990), Descending Angel (1990), Knight Moves (1992), Chaplin (1992), A Walk on the Moon (1999), Unfaithful (2002), Must Love Dogs (2005), Hollywoodland (2006)

QUOTE: "I really went for it in Walk on the Moon. I was saying, "Come on, guys, let's get it on tape now, before the fall of the empire!" My character had to absolutely cross the line of propriety. You can't sit there and go, 'I don't wanna show my nipple!' "

An actress whose sultry looks and versatile talent has made her into perhaps the biggest and most desired movie star of our times, Angelina Jolie has never let inhibition get in her way while showing some skin in almost a dozen pictures, the most memorable of those the made for TV biopic Gia, which earned her a Golden Globe award.

FILMS IN WHICH HE/SHE HAVE APPEARED NAKED: Cyborg 2 (1993), Hackers (1995), Foxfire (1996), Mojave Moon (1996), Gia (1998), Hell's Kitchen (1998), Playing by Heart (1998), Pushing Tin (1999), Original Sin (2001), Beyond Borders (2003), Taking Lives (2004), Mr. and Mrs. Smith (Unrated) (2005)

QUOTE: "I love doing lesbian love scenes. Before I did my lesbian scenes in Gia, I talked to actresses who said love scenes are easier with another woman than a man. Bound's Gina Gershon and Jennifer Tilly said they'd lie there and discuss the sale at Barney's between takes."

The former BMX Bandit turned Oscar winning Hollywood superstar has had a long history of disrobing in front of the camera, from her early work in Australian productions Windrider and Bongcock Hilton to big budget films such as Cold Mountain. Her most memorable nude scenes are found in Stanley Kubrick's erotic thriller Eyes Wide Shut, where she showed plenty of skin alongside ex-hubby Tom Cruise.

QUOTE: "Honestly is nudity onscreen that big a deal? I think you say you're going to do something for a film because you believe in it artistically and you don't censor yourself emotionally."

Much like Helen Mirren, veteran actress Charlotte Rampling has not let age stop her from continuing to appear nude in film, as Swimming Pool and Twice Upon a Time clearly shows. In her early years she took on many risqué roles, most notably as a former concentration camp inmate who develops a sadistic sexual relationship with her former guard (Dirk Bogarde) in The Night Porter. The film features an infamous scene where Rampling dances and sings topless in a Nazi outfit.

FILMS IN WHICH HE/SHE HAVE APPEARED NAKED: Tis Pity She's a Whore (1971), Giordano Bruno (1973), The Night Porter (1974), Zardoz (1974), La Chair de l'orchidee (1975), Yuppi du (1975), The Purple Taxi (1977), Tristesse et beaute (1985), On ne meurt que deux fois (1985), Max mon amour (1986), Hammers Over the Anvil (1993), Signs and Wonders (2000), Under the Sand (2000), Swimming Pool (2003), Twice Upon a Time (2006)

QUOTE: "There are now different subjects coming up for us older women that certainly didn't before. Of course, sexuality and sensuality have always been forms that film is obsessed with, but it used to be a form for younger women because, well, they were much prettier, but now directors and audiences are using it to explore older women - it may not be quite so pretty but my God that won't stop me from investigating it."

A criminally underrated and dedicated method actress, Jennifer Jason Leigh has played a rogue's gallery of prostitutes, junkies, and all around fragile characters who all share one characteristic: they love to get naked. And so Leigh obliges taking off her clothes in a whopping 19 films. In fact, a Jennifer Jason Leigh film without some skin shown is something of an abnormality.

FILMS IN WHICH HE/SHE HAVE APPEARED NAKED: Eyes of a Stranger (1981), Fast Times at Ridgemont High (1982), Death Ride to Osaka (TV) (1983), Flesh + Blood (1985), Sister Sister (1987), Heart of Midnight (1988), Last Exit to Brooklyn (1989), Miami Blues (1990), Backdraft (1991), Crooked Hearts (1991), Rush (1991), Single White Female (1992), Mrs. Parker and the Vicious Circle (1994), Georgia (1995), The Gulf War (TV) (1998), The King is Alive (2000), Skipped Parts (2000), The Machinist (2004), Margot at the Wedding (2007)

QUOTE: "People can have so many ill-conceived ideas about me based on the parts that I play. I've had guys, when I've been single, come out of the woodwork to date me and I've found out very quickly that they were expecting some kind of whirlwind, some dramatic crazy person - and that's just not me."
