Peur Sur La Ville is one of my all time favourite films.  Think Dirty Harry (Don Siegel, 1970) meets giallo and you get some idea of what this film is about.  I am not one for hyperbole but the stunts that Jean Paul Belmondo performs in this film are jaw droppingly awesome.  He hangs off of the edge of high-rise buildings, walks along the top of a speeding train and dangles from a helicopter.  How this film has never received more exposure is completely beyond me.  I have been looking a poster for this film for some time but have been put of by the disappointing artwork on some of them.  I recently lost an auction for the original French poster but was very happy to find a US one-sheet poster in excellent condition on eBay this afternoon for a decent price.
