Me, Too, in the Mafia(1974)

Petty crook “Viffer” Hansen pulls off a daring $10 million swindle selling Copenhagen’s Rundetårn to an oil sheikh, then substitutes the loot with expertly forged bills thanks to his counterfeit friend Valde. Hounded by both the mob’s Don Luigi, who promised Viffer the hand of his shrill-voiced daughter Elvira as reward, and the betrayed sheikh’s thuggish enforcer Olfert, Viffer adopts a new disguise, suffers amnesia in a madhouse, and narrowly escapes to face the final showdown when Luigi and Elvira arrive in Denmark to collect on his broken promise.
