Cactus Flower (1969) -

A hoary sex comedy that neither especially sexy nor especially comedic. The stagy, farcical conceit is this: Julian (the curiously cast but comedically expert Walter Matthau) is a sexy, swinging dentist -- yes, that Walter Matthau -- who's been seeing a quirky flower power pixie (Goldie Hawn, at the height of her exceptional kooky charm) who he's beginning to fall in love with. At the same time, his devoted nurse Stephanie (Ingrid Bergman, surprisingly charming in this light comedic role) is completely in love with him -- yes, that Walter Matthau, fending off Goldie Hawn and Ingrid Bergman. Hawn's Toni places great emphasis on truthfulness, which poses a problem for Julian because he lied about being married when he started the relationship with Toni. Now he wants to get serious, but has to reveal his lie. So he enlists his trusty nurse Stephanie to pose as his wife as part of his effort to get Toni to agree to marry him. And madcap hilarity ensues. Supposedly. I really don't care. The story's about as rich as an episode of Love American Style. The only thing to recommend this film -- aside from a kicky interior or two -- derives from the warm, humane performances of Hawn and Bergman. They're sweet and funny and you end up wanting both to be happy, which helped me to survive to the end of this otherwise stunted little late 1960s bit of utterly conventional unconventionality.
