"That's Amore", sung by Dean Martin, became a multi-million seller and one of his signature songs. The tune also appeared in the closing credits of "La ventana indiscreta (1954)" and is regarded as the theme song to "Hechizo de luna (1987)." An instrumental version can be heard in "Te veré en mis brazos (1958)."
The Central Intelligence Agency was concerned about the portrayal of race relations in Hollywood films, particularly for foreign consumption, and in the early 1950s quietly contacted a number of film studios about using more African-American actors in small, subtly positive roles.

The plaid background of the opening credits is likely a nod to the often loud and garish designs of golf trousers at the time.
