In March 1988, a preservation and restoration project was started by The National Center for Film and Video at The American Film Institute, in conjunction with The International Museum of Photography at George Eastman House and The Museum of Modern Art. It was completed in 1989. Milestone Film and Video added a music score by
Mark Izu in its 50-minute release of 2005, with an extra 3 minutes added for restoration credits and explanatory remarks.
