At the end, one can see the building where Nelly is living, and at the ground level there is a cinema whose frontage says: "Pierre Richard ...und jetzt das Ganze nochmal von vorn..."
In Nice, Pierre and Aldo watch a group of men playing the "pétanque", a traditional french game. One of them walks among players in an arrogant way, and someone says ironically : "They call him Trinita !", which is the (here translated) french title for this movie.
Disguised as a fireman, Pierre attempts to climb up the hotel wall to reach Agnès' bedroom. He thinks, "In a few seconds I would climb down, my beloved in the arms, like Steve McQueen in the Towering Inferno."
