The 1921 Rumpler Tropfenwagen, in the movie Metropolis. The movie
http://en.wikipedia.org/wiki/Metropolis_(film) was so visually stunning it's still on a lot of top 100 important fim lists. Because it was filmed in Germany post WWI, and so many were unemployed, extras were eager to get a job at near nothing pay... and the director employed an unbelievable 26,000 men as extras, 11,000 women, and 950 children... about 38 thousand extras. I haven't seen it yet myself.
