Cactus Flower

Bachelor dentist Julian Winston (Walter Matthau) wants an excuse to keep from marrying his flighty younger girlfriend, Jill (Goldie Hawn), so he calls upon his stoic receptionist, Stephanie (Ingrid Bergman) to masquerade as his wife. Much to his surprise, Stephanie emerges from her shell during the process, which complicates matters for the already bewildered ladies' man. This comedy gem, adapted from a hit Broadway play, earned Goldie Hawn a Best Supporting Actress Oscar.
