구봉서의 벼락부자(1961) / An Upstart ( Gu Bong-seo-ui Byeorakbuja )

A salaryman too broke to cover his lodgings inherits a fortune from an American officer whose life he saved in the war, on the condition that he spend the lot on enjoying himself inside a year. Politicians, film producers, beggars and inventors form a queue at his boarding house, in a broad money satire carried by the comedy trio of Kim Hee-gap, Koo Bong-seo and Kwak Kyu-seok.
