The film is based on the softcore graphic novel of the same name by Italy's master in erotic comic art, Milo Manara. The story location was moved from Italy to New Orleans for the movie for budgetary reasons.
Debra Lamb'a debut.
Toni Naples' first nude scene. She was part of footage shot to insert into the film for U.S. distribution. She agreed to do the nudity because she needed the money, but asked them not to list her name in the credits.
Producer Alan Siritzky said he had a tough time finding an actress to play lead character Claudia Christiani. He searched all over the world for an gorgeous actress who could play an uptight woman, but was also capable of really becoming wild in the sex scenes. Then Swiss Playboy photographer Otto Wesser suggested Florence Guerin, who his friend Roman Polanski introduced him to a few years before when she was 16 years old. He said she was gorgeous and had already performed nude in previous films, so nudity wouldn't be an issue. A few weeks later, Siritzky met with Guerin in front of her apartment building on the way to the airport to fly to New Orleans for filming. He cast her on the spot and she flew to New Orleans a week later.
Le Declic was released in France during 1989. Producer Roger Corman's New Horizons company debuted the film in the U.S. as The Turn-On and spiced up the sexual action even more by hiring Steve Barnett to direct additional nude scenes with starlets Toni Naples, Debra Lamb and Maria Ford.
