Revealing mistake: Kevin McKidd's Scottish accent appears every now and then. For example in this episode, when he says that Marc Antony "negotiates with a whore and a dwarf at his side".
Factual error: Caesar was not murdered on the Senate floor, as depicted in the series. That was the conspirators' plan, but when they learned that Mark Anthony was coming to meet Caesar, they instead lured Caesar into the portico of Pompey's theatre and killed him there.
