Continuity mistake: The man holding the parasol at the start: In the close-up shots, he is right behind Batiatus, and in an overhead one he is further back.
Continuity mistake: Spartacus and Antoninus are kept to the very end as the slave army are being crucified. They both somehow manage to remain clean shaven despite walking for days on end.
