As several others here have stated, I too watched this movie when it originally aired on TV back in 1972 when I was 11 years old and it was very scary then and is pretty creepy today, now that I am in my 40's. Helen (Elizabeth Ashley) lives alone with her young daughter and she starts receiving creepy, threatening phone calls from "Michael", her nephew who supposedly died in a blizzard after running away from home 15 years earlier. The acting is good, especially a young Michael Douglas, but there were several things left unanswered, why did Michael run away, why after all these years do the phone calls start up, etc? But overall the movie is a good little flick to watch with the lights off. Enjoy!!!
