Re: Weird Thing in "The Naked Time"
Many films and TV shows have also used the trick of putting a small wire cage with a piece of dry ice in each actor's mouth to simulate a frigid environment.
That would make dialogue recording on set rather difficult, and all the scenes would have to be looped in post. Probably had to do that on most of Arnold's films anyway.
