Of the four stories included in "Intolerance" the one placed in Babylon around 539 B.C. obviously was the one on which most of the unprecedented budget was spent. A massive life-size set of the Great Wall of Babylon was constructed. When the movie was completed it was left at the corner of Sunset Boulevard and Hollywood Boulevard and became a notable landmark for many years during Hollywood's golden era, until it fell into disrepair.
3,000 extras were employed for the movie, which must have been quite the percentage of the Hollywood community at the time (in 1910 the population of Hollywood was only 5.000, but it would climb tot 35.000 in the ten years after). Among the extras were future stars and directors like Douglas Fairbanks, King Vidor, Erich von Stroheim, Tod Browning and W.S. Van Dyke (the last two also worked as second assistant directors for the movie).
