There appears to be two versions to the ending of this film. In the video tape and normal broadcast version the various cast members are driving from the Twain home. But in one version Inspector Wang's car passes a car with Sherlock Holmes and Dr. Watson heading towards the Twain home. When Willie Wang asks his father "Isn't that?" "Shouldn't we warn them?", to which Inspector Wang says "Be quiet, let them find out for themselves".
There is a version of the film where in the scene where Wang instructs the other detectives to go into the other room while his son covers up the body of Twain, the son finds a note in Twain's hand and smugly reports this to the others.
