La faute à Rio (1984)

Welcome to the most exciting and sensual city in the world... Rio De Janeiro! The ultimate naughtiness of Brazil's hottest town is captured in this wild and wacky, zany screwball romantic comedy with a red-hot cast that includes Michael Caine (The Cider House Rules), Joseph Bologna (Big Daddy), Michelle Johnson (The Glimmer Man) and Demi Moore (Ghost).

Upon arriving in exotic Rio, long-time friends Matthew (Caine) and Victor (Bologna) and their teenage daughters (Moore and Johnson) barely unpack before this infamous pleasure spot begins to cast it's torrid spell. Matthew quickly succumbs to Cupid's arrow, but when guilt gets the better of this married man, he vows to end the affair and keep it a secret... even from Victor.

But as his white lies grow, so does his libido, Matthew continues his indiscretion... until his wife shows up!
