언니는 말괄량이(1961) / My Sister Is a Hussy ( Eonni-neun Malgwallyang-i )

The judo-obsessed eldest daughter of a martial arts instructor would rather spar than marry, and once she does marry she throws her new husband across the yard the first time they argue. Her father settles it the way he taught her to settle everything, on the mat, and the film gets real comic mileage out of a household where marital disputes are decided by grappling.
