The document discusses the filmmaking techniques used to create a sense of mystery and tension in a thriller sequence. Extreme close-ups of strings were used at the beginning to encourage audience questions. Sounds of wind and rumbles were added to shots to make them feel creepier. Wider shots later revealed more context but still left questions unanswered. Close-ups of a character waking in the dark tent continued the mystery. A revealing wide shot showed the strings led to the tent indoors, furthering the intrigue. A close-up of the character picking up an axe built tension over an unknown threat. Silence during a walk heightened discomfort. The door handle turning on its own gave a thrill while maintaining the mystery.
