Peter Sellers could do just about anything and this film helped to prove that fact. With some white hair, a moustache, and spectacles, you thoroughly believe his transformation into Mr. Martin, a character at least twenty-five years older than the actor was at the time.
Although the title sounds like a sex romp, that's not the right description of this clever comedy with a somewhat dark theme. But BATTLE OF THE SEXES is about a power struggle between a man and woman. Martin is the faithful manager at the House of MacPherson, a Scottish firm that's been turning out tweed the same way for decades. When the new heir (Robert Morley) takes over, he brings in a domineering efficiency expert (Constance Cummings), an American no less, whose ideas threaten to ruin the company.
Martin is forced to act. While he seems like a quiet and unassuming sort, he actually has a lot of guile and cunning beneath his mild-mannered exterior. First he tries to get her fired, but when that doesn't work he decides that more drastic measures are called for - like murder. Martin comes up with what he believes is the perfect plan, and all he has to do is carry it out.
Do yourself a favor and watch it all unfold. Entertaining from start to finish, hilarious in several places, with a good supporting cast, and a plot that has a couple of surprises in store. Sellers proves yet again that he's a true comic genius. Three cheers for that, and four stars out of five for the film.
