The Mummy: The Animated Series It premiered on Kids' WB! On the The WB network on September 29, 2001. It is set sometime between 1920 and 1934. The characters and plot were derived from the film, but the series could not replicate its success, efforts to make it consistent with real-world features were almost non-existent as, for example, Lake Titicaca is described as both puma-head shaped and as being found below the ruins of Macchu Picchu (Episode: The Cloud People).
