The fourth film on Kinemacolor's release schedule for the week of March 28, 1913, was the Ruritanian romance An American Invasion. The hero is the prince of a mythical mittel-European kingdom. Throwing tradition to the winds, the prince willingly gives up his throne to marry a beautiful American girl. But before stepping down, he tries to convert his country into a democracy, which foments a brief but noisy revolution. An American Invasion was distinguished by the Kinemacolor photographic process, which used a combination of tints, lights, and filters to create the illusion of "natural" color.
