Needful Things was filmed in Gibsons, British Columbia, Canada. The lot where the antique shop was located was filmed at 529 Gibsons Way Road. The diner that Bonnie and Nettie worked at was at Molly's Reach, 647 School Road.
The theatrical release of the movie ran at exactly two hours. However, there was a lot of material left on the cutting room floor. TBS aired the complete three hour movie in a four hour time slot (with commercials) on May 22nd, 1996.
This movie bears some similarity to the film Pumpkinhead II: Blood Wings. Both movies were released in 1993. Both films involve a sheriff who was a former New York City Police Department officer who returns to his home town and ends up playing peace officer amongst the rowdy locals. Both characters also come face to face with a supernatural menace.
