Profiling Spartacus, the gladiator who led a slave revolt against Rome from 73 to 71 B.C. and whose story was dramatized in Stanley Kubrick's 1960 film starring Kirk Douglas. In this hour, re-creations follow the onetime Roman soldier and 70 or so other escapees from a gladiator school. At first, this ragtag band “doesn't have much choice except to fight dirty,” says historian Crispin Swayne. But guerrilla victories swell his army to 100,000, and it will take Rome two years to stop him.
