This movie was released about two weeks before the final episode of the TV series on which it was based aired. In the final (4th) season, the show was overhauled and many of the regular characters were dropped (although some came back during the season). Miss Brooks and Mr. Conklin moved to a private elementary school in the San Fernando Valley. The movie ignored all this and all the original regular characters were back at Madison High School for the conclusion of the Brooks-Boynton courtship. Perhaps 30 years later, the final season of the TV show would have been dismissed as a "dream."
Gale Gordon (Osgood Conklin) replaced Joseph Kearns (Mr. Stone) after his death, in the Daniel el travieso (1993) sitcom, as Dennis' neighbor, Mr. Wilson.
Richard Crenna's first film role.
Following the film's completion in September 1955, Al Lewis requested and received a release from the television show to concentrate on a film career. During its 1955-56 season, ratings for the television show were slipping and its last episode aired in September 1956, a few months after the film was released. The wisecracking English teacher remained in public memory for several decades afterward, and Eve Arden was especially loved and remembered for her portrayal.
