Diane Keaton at 57
Another veteran of “The Godfather,” Keaton plays a sophisticated playwright in Nancy Meyers’ 2003 rom-com “Something’s Gotta Give.” But she shrieks in horror when the character's future love interest (Jack Nicholson) gets a head-to-toe view of her just as she's about to step into the shower.
Sandra Bullock at 44
Like Cameron Diaz, Bullock waited until she reached her forties to strip for the camera — in the 2009 comedy “The Proposal.” Her reason was simple: The script required it. In an interview with Us magazine, she recalled thinking: “OK, there is no way to shoot this unless you are buck naked.”
Sharon Stone at 47
After her provocative leg-crossing scene in the 1992 thriller “Basic Instinct,” there was no way Stone could demur from shedding her clothes in “Basic Instinct 2,” even though the sequel was made 14 years later.
Helen Hunt at 49 and John Hawkes at 52
There’s nothing gratuitous about the nudity in “The Sessions” (2012), a moving yet lighthearted film about a middle-aged poet suffering from polio-induced paralysis who hires a sex surrogate in order to lose his virginity.
Jane Seymour at 54
Seymour refused to rely on a body double during the filming of the 2005 comedy “The Wedding Crashers.” She later said she was “100 percent happy” with that decision.
Helen Mirren at 58
Some predicted that her performance in the highbrow porn flick “Caligula” (1979) would make Mirren blush when an uncut version was released three decades later. But the show of skin in the 2003 comedy “Calendar Girls” — based on the true story of an unorthodox fund-raising effort for a local hospital — was all for a good cause.
Viggo Mortensen at 48
The slippery hand-to-hand combat between Mortensen — playing a heavily tattooed Russian gangster — and two Chechen hit men inside a steamy Turkish bath made David Cronenberg's “Eastern Promises” (2007) one of the more talked-about films of the last decade.
Sigourney Weaver at 49
She stripped down before suiting up to fight the extraterrestrial monster at the end of “Alien” (1979) and appeared nude nightly in 1984’s off-Broadway production of “Hurlyburly.” Then, in the 1999 drama “A Map of the World,” Weaver upped the ante.
Ellen Burstyn at 51
A decade after her Oscar-nominated performances as middle-aged moms in “The Last Picture Show” and “The Exorcist,” Burstyn played the title character’s wife — who’s caught on tape having an affair — in the1984 political thriller “The Ambassador.”
Monica Bellucci at 47
“A Burning Hot Summer,” a French drama that reached the U.S. in 2012, is said to have been inspired by Jean-Luc Godard’s “Contempt” — a New Wave classic still remembered for the singularly sexy image of Brigitte Bardot in the buff. You can guess who plays the Bardot role in this update.
Harrison Ford at 46
In Roman Polanski’s 1988 thriller "Frantic," Ford plays a respectable physician who tries to scare a couple of French thugs into thinking he’s a crazy American by confronting them naked (strategically shielded by a stuffed rabbit).
Kim Cattrall at 53
It wouldn’t be “Sex and the City” if Samantha (Cattrall) kept her clothes on. In the universally panned 2010 sequel to the movie spin-off of the HBO series, she surprises her boyfriend by serving as a sushi platter.
Julianne Moore at 41
A decade after her daring nude scene in Robert Altman's "Short Cuts," Moore did another one in Stephen Daldry's "The Hours" (2002). "People ask all the time if sex scenes and nudity are hard," the renowned actress once said. "What’s hard? Not the lines or the physicality, but the emotion."
Harvey Keitel at 53
Keitel appears naked even in the movie poster for Abel Ferrara’s down-and-dirty crime drama “Bad Lieutenant” (1992). A year later, at 54, he had a more romantic nude scene in Jane Campion’s “The Piano.”
Tilda Swinton at 52
Swinton may be one of the boldest actresses alive. Her most recent roles include Madame D, a dowager who’s romanced by the concierge in “The Grand Budapest Hotel,” and Eve, a sexy vampire in Jim Jarmusch’s “Only Lovers Left Alive.” The characters’ respective ages: ninetysomething and 3,000 years old.
