For those in the Los Angeles area, KABC will broadcast
Grave Secrets: The Legacy of Hilltop Drive, starring David Selby and Patty Duke on Monday, October 17, at 12:35 AM (local time).
Selby and Duke play husband and wife, and it's rather amusing to see all the tricks they use to get both of their faces in a shot since he's over a foot taller than she is.
If you're interested in getting a copy of this movie on DVD, don't fool with Amazon. They only offer them through third-party sellers.
Movies Unlimited is much more reliable for this title.
I have screen grabs from the film on my Selby site.
Click here. These are from a broadcast copy. I've not gotten around to making new ones from the DVD.
