An American in Rome (1954) on Netflix

Nando Moriconi is a young Italian living in the early '50s Roma. He is completely crazy for everything that comes from the States. He tries to speak American-English (the most funny ever), to wear like he thinks Americans do, to walk like John Wayne (!), trying to eat cornflakes with ketchup... His life is a complete parody of the real American way of life, which he couldn't ever get. Nando's, not so secret, dream is to go to the USA. To get it he goes to the Coliseum and threats to suicide if American Embassy don't give him the visa. But at this point Nando is very well known as a 'crazy-for-USA' boy and the troubles he provoked in the past, couldn't help him.
