Which actor starred as the title character in Kubrick's 1960 film Spartacus? Kirk Douglas did.

Douglas plays Spartacus, the enslaved Thracian gladiator who leads a major uprising against the Roman Republic during the Third Servile War. The film presents Spartacus as both a formidable fighter and a leader seeking freedom for people held in slavery.

Stanley Kubrick directed the 1960 epic, which was adapted from Howard Fast's 1951 novel. The ensemble cast included Laurence Olivier as Roman general Marcus Licinius Crassus, Jean Simmons as Varinia, Charles Laughton as Sempronius Gracchus, and Peter Ustinov as Batiatus, the owner of the gladiatorial school.

A common mix-up is to associate the title with one of the other major performers, especially Olivier or Ustinov. They play important supporting characters, but Douglas is the star in the title role. The film was also significant in Hollywood history because Douglas helped secure Dalton Trumbo's screen credit during the blacklist era.
