Matalo!
Matalo! (also spelled as Mátalo) is a 1970 Italian Spaghetti Western film directed by Cesare Canevari.
The film is considered among the most original western ever produced in Italy. It is characterized from a greater weight given to psychology over action, an almost total lack of dialogues, an innovative soundtrack and the use by the lead character of a boomerang as his only weapon.
It was shown as part of a retrospective on Spaghetti Western at the 64th Venice International Film Festival.
