Broadcast on network TV in the United States to fill a 200 minutes time slot; later cut to 150 minutes. An alternate 112 minutes cable-TV cut was released theatrically in Europe and is available on video in the USA. The 112 minute version contains an altered scene of Cully Sawyer threatening Larry Crockett with a shotgun. Larry holds the shotgun barrel in his mouth, though in the mini-series he holds the barrel in front of his face. There is also an extended scene of Bill Norton impaled on antlers. Also, Salem's Lot: The Movie has some different music from the mini-series version.
DVD contains 183 minute version which is the complete mini-series.
The VHS 1987 version omits the scene where Ben and Mark are in Mexico, and a vampirized Susan is laying down on a cot in a hut. Then, Ben enters the room and impales her in the chest with a wooden stake.
