The Fall of the Roman Empire (1964)
The Fall of the Roman Empire featured killer performances from Hollywood legends like Christopher Plummer, Alec Guinness, and Sophia Loren. The film is considered one of the best “sword-and-sandal” movies in cinema history. Despite its accolades, the box office saw losses up to $126 million dollars (adjusted for inflation) due to the extravagant set costs, which shattered records for being the largest outdoor film set ever.
