Brace yourself: In her upcoming movie, Mary-Kate Olsen locks lips with Ben Kingsley. Yes, the one-time adorable tyke turned teenage titan, and Gandhi. Not surprisingly, the film's a comedy.

Olsen is now 21. Kingsley is 63.

Their film, "The Wackness," is slated for release next year.

"There is a very passionate scene in the film, which we filmed last week," Kingsley, who won the best-actor Oscar for 1982's "Gandhi," tells the syndicated TV show "Access Hollywood" in an interview scheduled to air Wednesday.

"It went extremely well and she was very focused. She was very good, very professional. She was quite wonderful."

When asked if he thinks the scene will stir up controversy, Kingsley says: "I'm sure it will. (Her character) is this great free spirit, you know, she is equally seducing so it is a level playing field."

In the film, Kingsley plays a therapist who forms a friendship with a teenage drug dealer (Josh Peck) who trades pot for therapy sessions. Olsen portrays one of the dealer's customers, who winds up kissing Kingsley's character.

"It's for a few seconds and then we disappear and we never see each other in the movie," Kingsley says. "But she is a trigger into my quest for happiness."

Though brief, the scene left a good impression on him. "Mary-Kate has huge energy," he says. "She is very, very committed to her work."

Olsen, who rose to fame on TV's "Full House," was last seen on the big screen opposite her sister, Ashley, in 2004's "New York Minute."

Kingsley's film credits also include "House of Sand and Fog" and "Schindler's List."
