• Director O'Neil's insistence on being as realistic as possible nearly cost Clayton her life. The actress almost died in an accident in the earthquake scene, where a chandelier fell on her. • Four months, a then-unprecedented length of time, were required to recreate the disaster. • Lubin Studio reused some of its own 1906
newsreel footage of the quake aftermath. Most of the Lubin newsreel footage was destroyed in a later film vault fire. ==Preservation status==
