New York: Actress Natalie Portman and actor Ashton Kutcher's new movie No Strings Attached has plenty of sex in it.
Portman, 29, and Kutcher, 32, have been shown in various compromising clothes-free positions as they play a couple of friends with benefits in the raunchy R-rated trailer.
The actress is seen alternately lying naked in bed with Kutcher, sprawled on top of him in nothing but a brassier and making out with the actor in the shower.
One particularly salacious scene has the actress wearing 3-D glasses while kneeling in front of Kutcher's naked body as he stands before her.
Portman's production company, Handsomecharlie Films, is behind the Ivan Reitman-directed film, and the actress had recently told Vogue Magazine that her company will focus on producing raunchy films for women.
"We're very into female comedies; there just aren't enough," the New York Daily News quoted Portman as saying of Handsomecharlie Films.
"There's a difference between being in a bra and underpants as an object on a men's-magazine cover and playing yourself -- a woman with desires and needs who loves and laughs with her friends -- in a bra and underpants," she stated.
No Strings Attached premieres on January 21.
