Once Is Not Enough (1975)

Synopsis
In this high-suds potboiler based on the best-selling novel by Jacqueline Susann, Mike Wayne (Kirk Douglas) is a past-his-prime movie producer who lives to make his college-age daughter January (Deborah Raffin) happy. January is also very fond of her father, perhaps more so than would seem healthy to the casual observer. Desperate to keep financing the good life for his daughter, Mike weds Deidre Granger (Alexis Smith), a wealthy bisexual who isn't about to give up her long-term relationship with Karla (Melina Mercouri). January finds herself pursued by suave playboy David Milford (George Hamilton), but she's more strongly attracted to Tom Colt (David Janssen), a middle-aged alcoholic novelist who reminds January of her father. Brenda Vaccaro won a Golden Globe award (and received an Oscar nomination) for her supporting performance as the man-crazy editor of a fashion magazine. ~ Mark Deming, All Movie Guide
