[post_page_title]Prometheus[/post_page_title]
Like Alien, science fiction movie Prometheus was directed by Ridley Scott, so maybe it should have been expected that the director would really try to scare the actors.
There is a scene in the movie when a monster shoots out of a corpse’s mouth. Unbeknownst to the actors, Scott had rigged up a device that would really shoot the monster out of the mask. When it happened, the actors were completely unprepared, and they really jumped in fright.
