Why on earth did Robert Hossein have to get involved in that business? (no pun intended,since the movie deals with big business).A man of taste ,he probably could not say no to Sergio Gobbi,a drudge with whom he had already made dreadful flicks ("maldonne" "le temps des loups " in the sixties).He had probably forgotten he too was a fine film noir director as such gems as "toi le venin" and "la mort d'un tueur" bear witness.
"L'affaire" is an unpleasant mean little movie.A business man (Hossein) wants to take revenge on his own brother who had his family (wife and and daughter) killed,to latch on to the whole family business.So he begins the task,which involves man of straw,speculating on the Stock,compromising photographs,nothing new under the sun.
If you want to have a look at the famous "tour d'argent" restaurant,where the villain savors caviar with a wonderful view of Notre-Dame ,this dud might interest you.Otherwise,avoid this updated ridiculous "Roger la Honte" .
