L'aîné des Ferchaux (1963)

 

Broke French ex-paratrooper turned amateur boxer Michel Maudet becomes bodyguard for the fugitive corrupt banker Ferchaux.

Odd French road movie, which is staged mostly in the USA, has elegantly construed narrative, it's nicely directed with two good lead performers, but the protagonists are quite disagreeable characters, so that one hardly develops any empathy for them.

La tarantola dal ventre nero (1971)

An inspector investigates serial crimes where victims are paralyzed while having their bellies ripped open with a sharp knife.
