"Buried", "Frozen", "Phone Booth" and countless other horror/thrillers have tried their hand at the 'single location' genre as I'll call it. The genre is a problem in itself; relying exclusively on compelling characters, mysterious motives, or potential plot twists with the setting to provide exciting entertainment. For example "Buried" plays upon the charisma of Ryan Reynolds and his character's everyman plight. "Frozen" adds the wrinkle that the ski resort won't be open for another week and a blizzard is coming.
