Grace Kelly refused to smoke cigarettes in any of her films, but she made a slight exception for Hitchcock in the 1954 film "Rear Window". In one scene, she's seen with an unlit cigarette between her lips.

In the scene, the camera cuts to James Stewart, then back to Kelly. She is suddenly holding a lit cigarette, which she soon puts out. This way, Hitchcock got his smoking scene, while Kelly never technically broke her non-smoking rule.

Additionally, when the entire movie is reviewed, "Rear Window" is an inventive thriller from director Alfred Hitchcock. It has a photographer, confined to his apartment with a broken leg, who thinks he sees a neighbor getting away with murder. He enlists his socialite girlfriend to dig up the truth. This is a technicolor suspense mystery which was written by John Michael Hayes and based upon Cornell Woolrich's 1942 short story 'It Had to Be Murder'. Originally released by Paramount Pictures, the film used some of Hollywood's most popular stars (Stewart, Kelly, Wendell Corey, Thelma Ritter, and Raymond Burr).

The film is considered by critics and movie scholars to be one of Hitchcock's best. It received 4 Academy Award nominations and was ranked number 42 on the America Film Institute's (AFI) 100 Years...100 Movies list. It is number 48 on the 2007 updated list. In 1997, "Rear Window" was added to the United States National Film Registry in the Library of Congress as being "culturally, historically, or aesthetically significant".
