Bundle of Joy

Bundle of Joy 1956 is a Technicolor musical remake of the comedy film Bachelor Mother 1939, which starred Ginger Rogers. It stars Eddie Fisher, Debbie Reynolds, and Adolphe Menjou. An unmarried salesgirl at a department store finds and takes care of an abandoned baby. Much confusion results when her coworkers assume the child is hers and that the father is the son of the store owner.

Carrie Fisher tells the story in her memoir and subsequent documentary film Wishful Drinking 2010 that Reynolds was pregnant with her during production of this film.During production, director Norman Taurog was in the early stages of Alzheimers disease. Very little was known about the illness at the time, so Debbie Reynolds and the rest of the cast and crew just coped with his unexplained memory losses and constant repeated instructions. ........
