With permission graciously granted by Eureka / MoC, here is the background of the restoration history of Murnau's Sunrise:
The following text by David Pierce details the history of the 2003 Sunrise film restoration. Pierce is the former curator of the National Film and Television Archive (NFTVA) and these notes were prepared for a British Film Institute screening in 2003.
Unlike many other films of the silent era that disappeared soon after their release, Sunrise has never been "lost," as the film has been available from the Museum of Modern Art Dept. of Film's Circulating Film Library since 1936. However, the original negative for Sunrise and most of the other silent and early sound films produced by the Fox Film Corp. were destroyed in a disastrous fire on July 9, 1937 at Fox's storage facility in Little Ferry, NJ.
Prints of Sunrise shown in recent years have not been satisfactory -- either contrasty and washed out, or grey and lacking any true blacks, removing all of the photographic elements that are the film's strength. All of the copies suffered from an overly noisy soundtrack.
As the 75th anniversary of the Academy Awards approached (2003), the BFI's NFTVA, the Academy Film Archive, and Twentieth Century-Fox joined together to re-examine Sunrise, and create new preservation elements on the film.
The film survives in two versions -- the American and European release editions. Sunrise was filmed as a silent, and the commercial need to add a Movietone soundtrack blocked a portion of the left side of the image, placing the compositions slightly off-balance. The European release of Sunrise was silent, so the image was intact. However, this edition used footage filmed by a second camera from slightly different angles, and the editing of the shots was different.
The best surviving elements of Sunrise have been two di-acetate (non-flammable) prints with the Movietone soundtrack made in 1936, held by the UCLA Film and Television Archive and the NFTVA. The UCLA print had to be destroyed in 1992, suffering from advanced decomposition due to vinegar syndrome.
In 1995, Kevin Brownlow and David Gill of Photoplay Productions prepared a new print of Sunrise as the Channel 4 silent form showing at the 1995 London Film Festival. After examining material held at Twentieth Century-Fox and archives around the world, they chose to work from 35mm material held at the NFTVA. The print was made from a fifth-generation negative that the NFTVA had acquired from the Museum of Modern Art, with sections copied from the 1936 di-acetate print. This project included a stereo recording of a new performance of the Hugo Riesenfeld original score conducted by Carl Davis.
The NFTVA 1936 print had begun to deteriorate when examined in 2002, so in discussions with Michael Pogorzelski, Director of the Academy Film Archive, and Schawn Belston, Executive Director, Film Preservation, Twentieth Century-Fox, the restoration partners decided that this project should focus on full preservation of this 1936 di-acetate print, including the first restoration of the original soundtrack.
Upon examination, it was apparent that the original negative to Sunrise was heavily worn when this print was made in 1936, so much of the wear -- scratches and an occasional splice -- were printed in. For some reason, possibly to keep the film in synchronization, each intertitle was preceded and followed by four of five black frames, which were subtly disconcerting during projection. In addition, the surface of the emulsion had begun to oxidize.
Under the supervision of Technical Manager DR Joao Oliveira, the NFTVA borrowed and examined other nitrate copies of Sunrise. A nitrate negative provided by the Cinematheque Francaise turned out to be a fifth-generation copy made in the late 1940s from a well-worn nitrate print. The Narodni Filmovy Archiv in Prague loaned a nitrate silent print made in 1927. This full-aperture print has Czech titles and inserts, uses second camera footage and uses some shots not present in the American release version. It is also missing almost a reel of footage. A fine-grain master positive held by Twentieth Century-Fox (and thought to descend from the UCLA di-acetate print) was examined by the Academy Film Archive, and determined to be fourth generation.
The restored version is based on the surviving 1936 print. The new negative was made on a step contact printer to retain maximum sharpness. The 1936 print was somewhat low contrast, so following consultation with Murnau scholar Luciano Berriatua, the contrast of the new negative was adjusted to match the Czech print.
The 1936 print had four shots with damage, so those shots were carefully replaced with duped sections from the Fox fine-grain by YCM Laboratories in Los Angeles. The original intertitles were scanned by Cinesite, digitally cleaned up and stretched to fit the original length of the titles, allowing elimination of the black frames in the 1936 print. The music score was copied from the 1936 print by 4MC in London. The sound restoration was supervised by the Academy Film Archive at DJ Audio in Los Angeles. Care was taken to leave the flaws and limitations inherent in the original Movietone process, and only remove the ravages of time.
The project has resulted in the creation of three preservation negatives, two fine-grain protection masters, and new prints. The result is the best possible using the technologies available in 2003.
