Lon Chaney wore a set of false animal teeth that hurt him so much that he could only wear them for a few minutes at a time. The teeth Chaney wore were not animal teeth, but were made of gutta-percha, a hard rubber-like material. What gave him the most discomfort were the wire loops around his eyes.
Is on AFI's "Lost Films" list.
It is believed that this film existed until 1967. Inventory records indicated that the only remaining print was being stored in MGM's vault #7 which was destroyed by fire in 1967. By that time, all other elements had been destroyed or were missing.
