What movie is the most historically accurate

Spartacus (1960) is often singled out for its relatively faithful depiction of the material conditions of slavery and aspects of daily life in the Roman world. The film pays careful attention to costumes, architecture, and the brutal routines of slave labor, conveying the social realities that made large-scale plantation slavery and gladiatorial exploitation possible. While director Stanley Kubrick and screenwriter Dalton Trumbo dramatize personalities, speeches, and political maneuvering for cinematic effect, historians such as Peter Green note that the movie’s representation of Roman material culture and the lived experience of enslaved people is notably convincing. In short: the film balances necessary dramatic invention with a convincing visual and moral depiction of Roman slavery. Reference: Peter Green, The Roman World.
