Brennus, Enemy of Rome and Battle of the Spartans) is a 1963 Italian peplum film directed by Giacomo Gentilomo.

The movie portrays the sack of Rome in 387 BC and was written by Adriano Bolzoni, Arpad DeRiso, and Nino Scolaro.

In Rome, high-ranking political and military figures engage in affairs with local noblewomen, and the barbarian easily takes advantage.

Brennus reacts by confronting and defeating the Romans, reaching Rome and obtaining a significant loot through plunder.

The movie's plot doesn't match the real events of the sack of Rome in 390 BC when the Senonian Gauls, led by Brennus, looted and occupied the city.
