The Evidence of the Film

The Evidence of the Film is a 1913 American silent short crime film directed by Lawrence Marston and Edwin Thanhouser. The editor (actress) is Florence LaBadie.
The only known copy of this film was rediscovered in 1999 on the floor of the projection booth in 2001 in a movie theater in Superior, Montana. And in 2001, this film was selected for preservation in the United States National Film Registry by the Library of Congress as being “culturally, historically, or aesthetically significant”.
