** The Aboriginal character's dialogue (and Tegan's when she [[SuddenlyAlwaysKnewThat demonstrates she can speak his language]]) was originally scripted as plausible-sounding gibberish.

The one they settled on was Tiwi as filmed.

** Stratford Johns was supposed to wear a more encumbering mask much like those worn briefly by his co-stares playing Persuasion and Enlightenment. Johns refused, fearing that the mask would hamper his performance. As a compromise, the makeup department created a thin latex mask each day for him to wear. It was laborious to apply and could only be used once as removing it destroyed it, but it allayed his concerns about the mask.
