Pierre Richard could be the french cousin of Rowan Atkinson: both are comedy actors skilled in pantomime with Pierre being however more frenetic and twister like. Here there are some really great funny moments in which his absent mind brings chaos; but sometimes some jokes are much too long and for a result not that funny
So this movie is like a roller coaster: with up and down
I expected some nostalgic view of Paris in the 70s and there is little so I am unsatisfied ... but the movie being about the advertising world, we can have however a taste of what french society was in this decade. I also give good mention to his entourage: Blier is cool as his compromised boss and Preboit is as lunatic as Pierre so when the two are together, everything fails really hard!
