The 1970 movie "Waterloo" was one of the most intricately filmed war movies of all time. A story about Napoleon's famous last stand could not be told accurately without battle scenes on a grand scale. But these were the days before CGI and other computer wizardry, so Dino De Laurentiis had to get the extras -- lots of them.
Russian director Sergei Bondarchuk housed the troops in tents near the battlefield and trained them in the infantry tactics and weapons of the time, 1815. The men were able to grow their facial hair and live like Napoleonic-era troops. They were more than just glorified battle re-enactors, they became bona fide Napoleonic Warriors, learning drills as well as saber and bayonet tactics.
The total price tag of the film came to a whopping $40 million – $247 million adjusted for inflation. The resulting battle scenes are worth every penny. Aside from a few anachronisms, the battles are epic depictions of the French Empereur's last 100 days.
Take that, Peter Jackson.
