Cactus Flower

Matthau is the dentist who, in order to avoid commitment, tells his girlfriends that he is married with children. However, when he finally agrees to tie the knot, and his chosen one Hawn insists on meeting his first wife, he is forced to have nurse Bergman play the part. Of course as the lies continue, matters only become more complicated, especially as stuffy Bergman discovers a world she has so far avoided. Quite amusing, but Matthau and Bergman don't really match and for once it is Hawn, in her debut feature, who saves the day.
