• The inspiration for this film came from D.W. Griffiths surprise at the loud protests against his previous film, The Birth of a Nation (1915). In response to those attacks, he wanted to illustrate the problem with intolerance to other peoples views.
• The massive life-size set of the Great Wall of Babylon, seen in the fourth story, was placed at the corner of Sunset Boulevard and Hollywood Boulevard (in Hollywood, California) when the movie was completed. It became a notable landmark for many years during Hollywoods golden era. It actually stood on the lot of the studio on Prospect Avenue near the Sunset & Hollywood Boulevard junctions in the eastern end of the city. It was the first such exterior set ever built in Hollywood. Falling into disrepair, it was eventually torn down. Years later, this same Babylon set was replicated as the central courtyard design for the new Hollywood & Highland complex in Hollywood, which opened in 2001.
• After filming wrapped, the Los Angeles Fire Department cited the Babylonian set as a fire hazard and ordered it to be torn down. D.W. Griffith discovered that he had run out of money and was therefore unable to finance its demolition. The set stood derelict and crumbling for nearly four years until it was finally taken down in 1919. By then it had fallen apart enough for it to be dismantled at a sufficiently low cost.
