On a Clear Day You Can See Forever is a 1970 American musical/romantic fantasy film directed by Vincente Minnelli. The screenplay by Alan Jay Lerner is adapted from his book for the 1965 stage production of the same name. The songs feature lyrics by Lerner and music by Burton Lane.
At the behest of her ultra-conservative fiance Warren, scatter-brained five-pack-a-day chain smoker and clairvoyant Daisy Gamble attends a class taught by psychiatrist Marc Chabot for help in kicking her habit. While undergoing hypnosis, it is discovered she is the reincarnation of Lady Melinda Winifred Waine Tentrees, a seductive 19th century coquette who was born the illegitimate daughter of a kitchen maid. She acquired the paternity records of the children housed in the orphanage where her mother worked and used the information to blackmail their wealthy fathers. She eventually married nobleman Robert Tentrees during the period of the English Regency, then was tried for espionage and treason after he abandoned her. As their sessions progress, complications arise when Chabot begins to fall in love with Daisy's exotic former self and Daisy begins to fall for him, and his university colleagues demand he either give up his reincarnation research or resign his position with the school. While waiting for Chabot in his office, Daisy accidentally hears a tape recording of one of her sessions; and when she discovers Chabot's interest is limited to Melinda, she storms out of the office. When she finally returns for a final meeting with him, she describes fourteen additional lives, including her forthcoming birth as Laura and subsequent marriage to the therapist in the year 2038.
