Mr. Gillette had nothing to do with the razor blades; he was a well-known Sherlock Holmes actor in the early years of the film. He used the money he earned from this to have this replica of the castle built. He must have been quite playful, as there was a small steam train in the garden that transported guests (the locomotive is in the information center).
