Operation Cupid [1960] [DVD]

Charlie Stevens, a hard-up Cockney wheeler-dealer, unwisely accepts a matrimonial agency as payment of a gambling debt. He discovers that the business is practically worthless, so, when Mrs Mountjoy, a wealthy widow, comes in search of a husband, he decides to pose as a South African millionaire in order to marry her himself. He is helped (or rather hindered) in this ruse by two dense side-kicks called Cecil and Mervyn.
