There's a certain level of uneasiness to seeing the people in the room acting very posh and professional and Craig Charles having fun with the crowd while chaos is ensuing in the house.
The Burning 9/17/18
The film doesn't have any 'proper' kills until the 50 minute mark, so we spend tons of time getting to know these characters better.
Wait Until Dark 5/16/18
The film does a fantastic job of being suspenseful, with the robbers getting more aggressive and violent as the film goes on.
