Bernardine is a 1957 film directed by Henry Levin and starring Pat Boone, Terry Moore, Dean Jagger, Dick Sargent, and (in her last film, after a 19-year absence) Janet Gaynor. The 1952 play upon which the movie is based was written by Mary Coyle Chase, the Denver playwright who also wrote the smash hit Broadway play Harvey. The title song, with words and music by Johnny Mercer, became a hit record for Boone.
