Forever, Darling is a 1956 American fantasy romantic comedy film directed by Alexander Hall, written by Helen Deutsch, and starring Lucille Ball, Desi Arnaz, and James Mason.

[2] After five years of marriage, chemical engineer Lorenzo Xavier Vega (Desi Arnaz) tends to neglect his wife Susan (Lucille Ball) in favor of his work.

When she wishes aloud that she had a more attentive spouse, her Guardian Angel – coincidentally the mirror image of her favorite movie star (James Mason) – appears.

The script initially titled Guardian Angel had been written by Deutsch in the 1940s as a vehicle for William Powell and Myrna Loy and had been languishing at Metro-Goldwyn-Mayer for several years.

Arnaz felt the script was weak, and he brought in I Love Lucy writers Madelyn Pugh and Bob Carroll, Jr. to make uncredited changes; the duo's contribution was the slapstick camping sequence in the final third of the film.

[6] The title song, with lyrics by Sammy Cahn and music by Bronislau Kaper, was recorded by both Arnaz and the Ames Brothers, who performed it over the opening credits and ultimately had the bigger hit.

The tune became an Arnaz family tradition, sung by Desi at special events, including his daughter Lucie's marriage to actor Laurence Luckinbill.
