Hitchcock's cameo comes early in Strangers on a Train. He is seen boarding a train carrying a double bass.

Hitchcock cast his own daughter as the younger sister of Guy's girlfriend. Patricia Hitchcock also appeared in her father's Stage Fright (1950) and Psycho (1960).

Similar to the scene of Bruno at the Morton's party, Hitchcock enjoyed showing people in social situations how to strangle someone. Also, a famous sequence of photos by Philippe Halsman shows Hitchcock doing various things to a bust of his daughter, including strangling her.

Advertisements for the film showed Hitchcock inserting the letter "L" into the word "Strangers" in the title to make "Stranglers."

In 1956, Ruth Roman and her son were among the hundreds of passengers rescued when the luxury liner Andrea Doria collided with another ship and sank.

Laura Elliott, who played Guy's murdered wife, is best remembered under her other professional name, Kasey Rogers, as Louise Tate, wife of Darren's boss on the TV series Bewitched.

Marion Lorne, who played Bruno's mother, also appeared on Bewitched for several seasons as Samantha¿ dotty old Aunt Clara.

Hitchcock and cinematographer Robert Burks worked together 12 times. Burks shot every one of Hitchcock's films between this picture and Marnie (1964), except for Psycho (1960). He was Oscar-nominated for this film and Rear Window (1954) and won Best Color Cinematography for To Catch a Thief (1955).

Composer Dimitri Tiomkin also wrote the scores for the Hitchcock films Shadow of a Doubt (1943), I Confess (1953), and Dial M for Murder (1954).

Leo G. Carroll appeared in five other Hitchcock films, including his role as the murderous Dr. Murchison in Spellbound (1945).

Several of Raymond Chandler's novels have been made into movies, including Farewell, My Lovely (1975, and as The Falcon Takes Over, 1942, and Murder, My Sweet, 1944), The Big Sleep (1946 and 1978), Lady in the Lake (1947), and The Long Goodbye (1973).

Chandler also wrote the screenplays for Double Indemnity (1944), The Unseen (1945), and The Blue Dahlia (1946).

Raymond Chandler on writing for film: "They hire writers as a necessary evil because all the brilliant second-guessers, who can tell you what is wrong with what you do, can't do anything themselves. They hire writers, I said, and sometimes at a high salary; but they hate them every minute. They would rather save a thousand bucks by cutting off a writer before he has time to catch his breath than save fifty thousand by using their brains during production."
