Kampf Um Rom (aka The Last Roman) (1968)

Set in the 6th century A.D., the Roman Empire is a shadow of its former self as the Ostrogoths rule over it. When the Ostrogoth king dies, his two daughters (Harriet Andersson, Honor Blackman) fight over who will be Queen. The devious leader (Laurence Harvey) of what remains of Rome takes advantage of this by playing both sides while the Emperor (Orson Welles) of the Byzantine empire also has designs on Rome. Based on the novel THE STRUGGLE FOR ROME by Felix Dahn and directed by Robert Siodmak (THE SPIRAL STAIRCASE) in his swan song as a film director. From 1943 to 1952, Siodmak made a series of excellent films in the U.S. but after THE CRIMSON PIRATE, he returned to Europe to make movies. Siodmak wasn't content with the script but proceeded anyway. As an epic (its 3 hours long), it's visually impressive and structurally incoherent. Unless you're a Roman history buff, you may well be confused about the Roman, Goth and Byzantine triptych's power battle. With Sylva Koscina, Michael Dunn, Robert Hoffman, Ingrid Boulting, Lang Jeffries and Florin Piersic.
