Cartoon historian David Gerstein has been rummaging through the Library of Congress and has come up with the dialogue cutting continuities for several MGM cartoons and has noticed discrepancies between the films as they exist today, and these original copyright documents. As noted on Cartoon Brew back in June 2005, MGM not only retitled their cartoon shorts for reissue, but would go in and edit out or reanimate topical gags for rerelease. These copyright cutting continuities are important because they describe scenes and gags which no longer exist. Due to a vault fire in the 1970s, the original negatives for the pre-1951 MGM cartoons no longer exist. Unless rare nitrate projection prints are found, these documents are now the only record of the original films.
Thad Komorowski has just posted the continuity for Avery’s Dumb Hounded. Compare it to the re-release version of the cartoon itself to note the differences. Apparently a whole new opening sequence was added. Thanks to David, for sharing his diligent research with the animation community. Now I’m wondering if that fabled “marriage ending” to Red Hot Riding Hood is in the original release?
