Horror movies are big business, but that doesn't mean you need big-name directors or stars. All it takes to make an effective horror film is a great premise, a bold vision and many, many late nights.

Among the greatest recent additions to the genre are "It Follows" and "The Babadook," low-budget movies that created a big, disturbing impact.
