Maurice Poli (born 2 December 1933) is a French actor, mainly active in Italian productions.
He is regarded as one of the few actors to have taken part in virtually all the genres developed in Italy in over more than thirty years.Born in Bizerte, Tunisia, Poli made his film debut in 1961, in a very small role in Mauro Bolognini's The Lovemakers.
He later alternated leading roles and supporting roles, being often cast as a tough guy or a villain.
Following a fashion of the time for American-sounding stage names, in the second half of the 1960s he was credited Monty Greenwood in several spaghetti westerns.After retiring, he took up residence in Rome, Italy and devoted himself to his lifelong hobbies of geology and archaeology.
