Graziano Mesina was a "bandit" who became a celebrity in Italy in the 60ies, when he joined forces with a Spanish adventurer Miguel Atienza, and kidnapped several people, escaping from prison a dozen times.
This movie is a bit weak in the analysis of the Sardegna world of bandits, it shows the events in a bit haphazard way without giving background information. I have enjoyed much more the similar movie "Barbiagia" with Terence Hill.
Ugo Cardea is a decent actor but he is clearly making an effort to speak with a Sardegna accent - not to mention Giuliano Esperanti who is clearly NOT Spanish and simulates a very dubious Spanish accent while impersonating Miguel Atienza.
