Another bit of classic 70's horror, filmed on location in San Antonio, Castroville, Bandera, and Leakey, Texas, released in 1975. In the wake of The Texas Chainsaw Massacre, Central Texas seemed to be the new Transylvania. For those of us from the area, it added another layer of fear, seeing such familiar terrain and people as the backdrop to a tale of terror, this being one of the worst kind: Satanic horror!
Folks from the San Antonio area might be amused to see the old Alamo Speedway at the beginning of the movie, along with a cameo by local legend/radio personality Ricci Ware as a racing official.
This is a genuinely scary and fun movie, with acting a cut above the usual of the genre, and a simple straightforward plot that keeps you hooked.
