Here's a nice clip of Susan Dey on the horror anthology series
Circle of Fear (
Ghost Story was the original title of the show) in 1973. This was Susan Dey's first TV appearance outside of
The Partridge Family (though she had a small role in the 1972 feature film
Skyjacked) and one of only two instances where she appeared in a horror-related project (the other being the TV movie
Disappearance in 2002).
Edit: Also (as a Susan Dey fan on Facebook kindly pointed out), Susan Dey's 1995 TV movie
Deadly Love, about vampires and murder, should also rightfully be considered a horror-related project. My mistake for not including it!
In the
Circle of Fear episode called 'Doorway to Death', Susan Dey plays big sister to two younger kids, played by Leif Garrett and Dawn Lyn. Luckily, Susan Dey already had a bunch of experience acting with children since she had been doing it on
The Partridge Family since 1970!
