I've seen this one a few times over the years and wish it would come out in DVD. Natalie Wood was never more beautiful, and the battle of the sexes was never more fun. It's great to see a love story that doesn't resort to foul language or adult humor, but simply witty dialog and the vagaries of human nature.
Tony Curtis plays a tabloid reporter trying to get the goods on Helen Gurley Brown (played by Natalie Wood) and her personal life to find out if she actually knows anything about sex and relationships. To this end, he impersonates an acquaintance (played by Henry Fonda) whose having problems with his jealous wife (played by Lauren Bacall) so that he can pose as a patient and seek her advice.
The confusion caused by this impersonation just leads to more problems. However, this is just a sideshow to the reporter's seduction of Dr. Brown and the glorious mayhem that ensues.
Her constant comparisons of Tony Curtis to Jack Lemmon (Curtis' co-star in Some Like It Hot) will appeal anyone who's seen that classic.
