This is surely one of the most popular "Carry Ons", a spoof on the notoriously expensive CLEOPATRA (1963) and was in fact shot on abandoned sets built in London for that film! The cast is in top form here Sidney James is Marc Antony, Kenneth Williams Julius Caesar, Joan Sims is Calpurnia (Caesar's wife), Charles Hatwrey Seneca (philosopher and Sims' father); Kenneth Connor (as Hengist Pod, the inventor of a square wheel and who eventually does a stint as Caesar's 'invincible' bodyguard) and Jim Dale are featured as early Britons; Amanda Barrie who had previously appeared in CARRY ON CABBY (1963) makes for a delightful Cleopatra.
Though emerging to be somewhat patchy considering its reputation, there are some undeniably uproarious moments throughout the Roman soldier throwing a shield at Dale during a scuffle and hitting Connor squarely in the face; the famous carpet-rolling scene introducing Cleopatra in the 1963 Hollywood epic being directly lampooned here by having the Egyptian queen roll under a table replenished with food and spilling its contents onto herself and the floor; untrue to history, Antony connives with Cleopatra to murder Caesar and become Emperor himself she suggests using a poisonous asp and hands him one from a basket, which he mistakes for a local delicacy and promptly bites off its head! Talbot Rothwell's script also includes a running gag involving the famous "Friends, Romans, Countrymen" Shakespearean speech, as well as an in-joke wherein a couple of traders merge their business to be known from then on as "Marcus & Spencius"!
