Flying Circus (1965)

By day he runs a successful circus, but by night Thor has been building a magnificent robot which he plans to use to locate and dig up the ancient tomb of Gangez. Within the tomb, Thor believes, is the secret to creating an elixir which will guarantee immortality. The heroic Daula Rao (Ranjan) is looking for this recipe as well, but his motive is to use the elixir to help mankind, while Thor wishes to use it to rule the world. A battle brews between good and evil, with Daula Rao helped along the way by a scientist, a pilot, a princess, and a dog.
