Lon Chaney Jr is back as The Mummy and this time out he does earn his paycheck with a much better performance than the last time. Perhaps the reason for this is that they actually give him some material to work with so that he has something to do instead of simply shuffling in the dust.
Like the last film, most of the action takes place in America but this time out they have bigger sets and lots of on location shoots. Jack Pierce's makeup is still a bit lacking, making the mummy look more like he's been mud wrestling rather than been covered with the dust of the ages.
Overall, The Mummy's Ghost is a much better film than The Mummy's Tomb and might even be better than The Mummy Hand. Yes, it's filled with lots of horror cliches and you know pretty much where the film is headed every step of the way but it's not a bad ride in spite of this.
