The movie deals with the great emperor of Rome , Marco Aurelio (Alec Guinness) , of the dynasty of Antoninos , formed by : Nerva , Trajano , Adriano , Antonino Pio , Marco Aurelio and Commodo (Christopher Plummer , though Richard Harris was originally cast and he withdrew because of artistic differences with the director) . After that , there happens several riots and coups d'etat until Diocleciano , who imposed peace and order with the Tetrarchy . Being dead Marco Aurelio , succeeded his son Commodo , a nutty gladiator emperor , he'll take on his sister Drusilla (Sophia Loren) and Livio (Stephen Boyd replaced Charlton Heston and he blamed the massive commercial failure for ruining his career) . They'll have to fight against German barbarians (commanded by John Ireland) and Persians (ruled by Omar Shariff).
In the picture there are struggles , epic events , a love history and being very interesting , in spite of the fact that the runtime is overlong : about three hours . Budgeted at about $20 million , this was Paramount's biggest flop of 1964 , its failure cost producer Samuel Bronston his Spanish production facility . Cast and support are frankly well . As Alec Guinness as a stoic and thoughtful philosopher emperor craving the ¨Pax Romana¨ (Latin for the "Peace in Rome¨) is top-notch . Christopher Plummer's interpretation as the nut-head son is first-rate , he was 33 at the time of filming , although his character Commodus became Emperor at the age of 19 ; while other main actors as Stephen Boyd and Sophia Loren are a bit wooden . James Mason as Marco Aurelio's broody and good adviser is excellent . This lavishly financed film was originally intended to be made after El Cid and to reunite Charlton Heston and Sophia Loren . The set for the Forum Romanum was actually being built when Heston rejected the script but expressed an interest in '55 Days at Peking' instead . Samuel Bronston immediately ordered that the work on the Forum be stopped and the landscaping and foundation work be adapted for the Peking set . After filming , the Peking set was torn down and replaced by the Forum , if you look carefully , both sets share a very similar topography . Colosanti and John Moore production design is breathtaking . Battles staged by Yakima Canutt are incredible and impressive . Scenarios are overwhelming : the Roman Forum , Roman Capitol , the temples...the sets are spellbound . Colorful cinematography by the great cameraman Robert Krasker is awesome , similar to Dimitri Tiomkin's fascinating and romantic musical score . Anthony Mann's direction in his last film is spectacular and outstanding . The motion picture didn't achieve success at the box office , it was a real flop and collapsed Samuel Bronston's empire . Rating : Above average . Well worth Watching . Very Good .
