Bachelor in Paradise is a 1961 American Metrocolor, CinemaScope romantic comedy film starring Bob Hope and Lana Turner. Directed by Jack Arnold, it was written by Valentine Davies and Hal Kanter, based on a story by Vera Caspary.

Vera Louise Caspary was an American writer of novels, plays, screenplays, and short stories. Her best-known novel, Laura, was made into a successful movie. Though she claimed she was not a "real" mystery writer, her novels effectively merged women's quest for identity and love with murder plots. Independence is the key to her protagonists, with her novels revolving around women who are menaced, but who turn out to be neither victimized nor rescued damsels.
