Five lousy gangsters are sick of constantly stealing money from banks and decide to specialize themselves in abduction of celebrities or important people. First, they kidnap Johnny Hallyday (who in the film sings the song that is sourced from the title of the film), then they fly down to South America where they confine illegally an ambassador for a revolutionary. Thus, they pocket enough dough to go on holiday in the Carabbean.
This comedy from Claude Lelouch bears his trademark. Everything is conceived and made with a naive perspective from the steps of the narration which seem sometimes approximative and lame in spite of its simple linearity to the moral of the film that celebrates complete disengagement in favor of money. The filmmaker didn't jettison gratuitous effects and sometimes, the actors don't properly pronounce their cues; so you have to be very attentive to decipher what they say. But, the film has funny moments and Lelouch wields nonsense with quite efficiency. His virtuosity with camera makes up a bit for the drawbacks of the story aforementioned and I will add this extra one: the cast is patchy. Lino Ventura is as usual great but Jacques Brel... well I largely favor him as a singer, songwriter. His talent in acting is another story.
Lelouch is Lelouch and this cynical comedy will rejoice his fans. If you're looking for a film rigorously made, it's not the right one.
