Kristen Stewart, On The Road
Bella Swan shed her Twilight purity to play Marylou, a gal with an insatiable appetite for sex. She shed her shirt for a few topless scenes along the way.

Jason Segel, Forgetting Sarah Marshall
The How I Met Your Mother funnyman showed it all off not once but twice in this comedy. Once while crying and once surrounded by puppets. Naturally!

Helen Hunt, The Sessions
In the film, she strips down to play a professional sex surrogate. And for her efforts she nabbed some Best Supporting Actress nominations and serious Oscar buzz.

Michael Fassbender, Shame
The X-Men star played a sex addict, so it's only natural that he'd go full frontal. He got a Golden Globe nomination and left everyone taking about his, well, member.

Anne Hathaway, Love and Other Drugs
The Princess Diaries star is all grown up and has no problem stripping down—if the role is right. Which it was in such films as Havoc, Brokeback Mountain and Love and Other Drugs.

Jake Gyllenhaal, Love and Other Drugs
Which brings us to Anne's costar, as the Prince of Persia hunk was in a constant state of nakedness (with at least one full on booty shot). God bless this movie. God bless it.

Marisa Tomei, The Wrestler
Play a stripper, get nominated for an Oscar. It's not the most fool proof method in Hollywood, but Tomei's turn as an aging stripper opposite Mickey Rourke did just that.

Ryan Reynolds, The Proposal
Van Wilder himself is no stranger to losing his pants, though usually it's in the name of comedy. Here, he had a butt naked run in with the equally nude Sandra Bullock.

Nicole Kidman, Eyes Wide Shut
It's not all sexy talk in this intense drama: Tom Cruise's then-wife was naked within the first few minutes of Stanley Kubrick's final film about a lusty couple.

Matthew McConaughey, Magic Mike
True Blood hunk Joe Manganiello may have been the stripper to show the most skin, but Mr. McConaughey rocked his thong best. And without a bongo drum in sight!

Julianne Moore, Boogie Nights
Mark Wahlberg's Dirk Diggler may give the money shot, sure, but prosthetics don't count on this list. Plus, Moore's porn star "Amber Waves" trumps him in sheer volume of screen time spent nude.

Kate Winslet, Titanic
"I want you to draw me like one of your French girls," Winslet's Rose cooed to her star-crossed lover Jack (Leonardo DiCaprio). "Wearing only this." (The "this" in question was nothing but a diamond.)

Angelina Jolie, Gia
The titular Gia references oft-troubled model Gia Carangi and one memorable scene features Jolie and Elizabeth Mitchell in a nude photo shoot. Followed immediately afterwards by a sex scene.

Charlize Theron, Monster
It's probably not the role you wanted to see the South African beauty get naked for (she packed on the pounds and transformed her cover girl looks to resemble the murder), but beggars can't be choosers.

James Franco, Milk
The former Spider-Man heartthrob isn't afraid to step outside his comfort zone for his art. For one, a skinny dipping scene while playing Harvey Milk's (Sean Penn) lover.

Richard Gere, American Gigolo
Gere plays a male escort in Los Angeles who sleeps his way to the top. But amid the nice cars and nice clothes, there was also a heck of a lot of nice onscreen nudity.

Sharon Stone, Basic Instinct
Sharon practically invented the crotch flash in this erotic thriller, which earned her a Golden Globe nom. And also a Razzie nom for her "Tribute to Theodore Cleaver." Uhhh.

Sacha Baron Cohen, Borat
If you remember one thing from the faux documentary beyond the grating impression of "Veeehry niiiiace!" it's surely the extended sequence of two men naked fighting around a hotel.

Halle Berry, Monster's Ball
2001 was the near of naked Halle: First, in Swordfish, where she appeared topless. And then in Monster's Ball, in an intense sex scene with Billy Bob Thornton. She won an Oscar for the latter.

Ewan McGregor in...Everything
Take your pick: Velvet Goldmine, Young Adam, The Ghost Writer, The Pillow Book, Trainspotting. Let's just say Mr. McGregor isn't shy about showing off little Ewan. And he doesn't seem to have plans of stopping anytime soon.
