Italian dramedy. It was distributed in English-speaking markets as The Last Night, but the literal translation is The Last New Year’s Eve.
Italians celebrate New Year’s Eve different ways – getting high, cheat on a wife, revenge, spy on a cute naked neighbor, suicide attempt, hire a gigolo or call girl, have a party, crash one, etc.
Johnny Moronic’s film clips can be found here.
The entire film is on YouTube for free, but the quality is not impressive.
