The most expensive film of the silent era was Ben-Hur (1925),  costing about $4 million—an astronomical sum in those days at twenty-five times the $160,000 average cost of an MGM feature.  It is unclear which sound era production superseded it as the most expensive film, although this is commonly attributed to Hell's Angels (1930), directed by Howard Hughes ; the accounts for Hell's Angels show it cost $ million, but Hughes publicised it as costing $4 million, selling it to the media as the most expensive film ever made up to that point.  The first film to seriously challenge the record was Gone with the Wind (1939), reported to have cost about $– million,  although sources from the time state that Ben-Hur and—erroneously— Hell's Angels cost more.  Ben-Hur was definitively displaced at the top of the chart by Duel in the Sun in 1946, meaning Ben Hur possibly held the record for 21 years.
Various factors enter into a city's cost-of-living for expatriate employees, such as monetary value, consumer confidence , investment , interest rates , exchange rates of the country's currency, and housing costs.
