Il tiranno di Siracusa (English Release Title: Damon and Pythias) is a 1962 Italian/American film directed by Curtis Bernhardt.

The film is based on the Greek legend of Damon and Pythias, and set during the reign of Dionysius I of Syracuse (432–367 BC).

Fellow Pythagorian Pythias is ordered to go to Syracuse and convince the philosopher Arcanos to return with him and take Protheus' place.

These two ruthlessly hunt down and destroy anyone involved in this "dangerous" philosophy, as the Pythagorians call all men brothers/equal and embrace pacifism over war and conquest.

Meanwhile, Pythias arrives in Syracuse, and meets streetwise local con man and bandit Damon.

Pythias is forced to fight Cariso himself, but Damon's gang and several other street people step in to help, killing the captain.

Dionysius accuses him of killing Cariso, in an effort to discredit his pacifism, but Damon's gang takes all the blame.
