Factual error: On the Amtrak train, "Vicki" sees a sign advertising downhill skiing trips to Victoria, BC. There are no downhill ski areas in Victoria, or close by, and Amtrak doesn't travel to Victoria.
Factual error: When Barnabus is talking to Carolyn (just before he goes out in the woods and kills the hippies) he says "I am a picker. I am a grinner. I am a lover. And I am a sinner. I play my music in the sun." These are lines from the song "The Joker" which was recorded in August of 1973 and released in October 1973. The song wasn't released for a full year after the events in the movie, which takes place in October, 1972. (00:56:50 - 00:57:12)
Factual error: The train sequences that are supposed to be in 1972 show Amtrak cars that were not built until the 1980s, and the rear (pusher) locomotive was not built until after 2000, as was the modified locomotive/control car in the front. The Amtrak graphics are from this century also. They went to the trouble to create 1972 Maine license plates for the vintage autos, and spent millions on effects, but they can't contact a historical society for the use of a correct coach for a day and search for stock footage of a train that's not 40 years too modern?
Factual error: Alice Cooper sings the song "No more Mr Nice guy." This song wasn't released at that time.
Answer: It's unknown. The original intention was to make Dark Shadows into a film franchise and that question probably would have been answered in the sequel. However, there have been no additional films made.
