 Following this, the witch doctor arrives and performs a ritual that summons an unnatural storm, with a bolt of lightning striking the rifle Sawyer left on Quatermain's grave.For the script, the character "The Invisible Man" was changed to "An Invisible Man" since Fox was unable to obtain the rights to the title character of H. G. Wells' 1897 novel "The Invisible Man", and his name was changed from "Hawley Griffin" to "Rodney Skinner".The Fu Manchu character was also dropped from the script.
