5. Titanic
And we have arrived at the number five were we find Titanic, a huge success, both critically and commercially.
It was the big success of James Cameron, before Avatar. Titanic had a budget of $200 million which made it one of the most expensive films ever created.
Much of the budget went on paying the small army of extras, founding the two months of overtime required to finish the shoot and on the wages of the stars and crew.
But wait, there is more. Another part of the budget went on creating the hugely detailed sets that appear throughout.
The biggest set included a 40-acre facility that contained two huge tanks that could contain more than twenty million gallons of water and a 90% scale replica of the starboard side of the ship.
The boat was needed for hundreds of different shots, while the tanks of the model were necessary so the director could shot the replica in water and allow it to sink at the end.
The total cost when adjusted for inflation of this elaborate set alone exceeded $30 million.
