From IMDb: Although there are rumors that Lon Chaney Jr.'s scenes in the "Mummy" series frequently used doubles for him, director Reginald Le Borg stated that Chaney did his own scenes in this film. #themummysghost#lonchaney#johncarradine #reginaldleborg
From IMDb: In the scene where Kharis trashes the Scripps Museum, Lon Chaney Jr. drove his fist through real glass--it was supposed to be breakaway glass, but the prop man forgot to replace it before shooting started--and a shard of it flew up and cut him through his mummy mask in his chin. In this scene, Kharis can be seen bleeding, and it's real blood. #themummysghost#lonchaney#johncarradine#reginaldleborg
