The Battle of the Sexes is a 1959 British black and white comedy film starring Peter Sellers, Robert Morley, and Constance Cummings, and directed by Charles Crichton.

A timid accountant in a Scottish Tweed weaving company cleverly bests a brash modern American efficiency expert whose ideas threaten his way of life.

Mr Martin, the accountant for a Scottish Tweed weaving company, is in Edinburgh buying whisky and cigarettes on the Royal Mile.

[5] Crichton liked the script, felt Robert Morley was "slightly miscast... but I think it was about the best performance Peter Sellers ever gave in his life.

[8] On its 1960 release, the film was very warmly reviewed by The New York Times, with critic A. H. Weiler calling it a "gentle, tongue-in-cheek ribbing that cleaves to the spirit, if not entirely to the letter of Thurber's lampoon.

"[3] Stanley Kauffmann of The New Republic wrote- The Battle of the Sexes, transfers James Thurber's story The Catbird Seat to Scotland and spins it out to unjustified length.
