Though Jenny (Marlo Thomas) is supposed to be a cinephile, the script makes a glaring error when the character compares a marital situation to the film Anything Can Happen (1952) "with Nicholas Ray and Judy Holliday." That film actually starred Jose Ferrer and Kim Hunter and was about an immigrant acclimating to American life. The film the screenwriter meant to cite was the same year's The Marrying Kind (1952), which starred Holliday and chronicled a troubled marriage. Her co-star in that film was not director Nicholas Ray, but actor Aldo Ray.
This was the first film directed by George Bloomfield starring Alan Alda, the second was TO KILL A CLOWN (1972).
Al Thomas and Estelle Winwood were hired to play Alan Alda's parents in the film, but their scene was cut from the finished film.
