This is one of those childhood films that has always stuck in my mind. As a kid, I was freaked out by gargoyles because of this movie (unlike the next generation who saw gargoyles as defenders of evil, thanks to a Disney series). Seeing it again as an adult is a different matter entirely...
For 1972, this was one helluva TV movie. The effects, though dated by today's CGI-laden standards, were spectacular -- and the Stan Winston created gargoyle suits still look good pretty damn today.
What the film lacks is a coherant story. The bare-bones 74 minute movie had potential to be so much better than 50's b-movie fare, but instead the filmmakers opted to skip a solid story and add in a group of bikers and other silliness that reflected the times. Cornel Wilde was probably in the late stages of his alcoholism, and it showed in his hokey performance as the lead. His lines are delivered with a wooden tone and no conviction. Jennifer Salt, who I liked in "Soap," seemed miscast here, though she was effective. The only really memorable human character is the horny lady that owns the motel which Wilde and Salt stay in. The REAL stars of the film were Bernie Casey, Richard Moll and all the other Gargoyles, hidden under latex costumes... with the ability to scare young children. By today's standards, this comes close to "The Creature from the Black Lagoon," "Them" and other '50s drive-in films.
Another person commented the similarities to the gargoyles and "Jeepers Creepers." While I agree that The Creeper had certain similarities, there was only one Creeper and the impact of that character certainly couldn't be what Gargoyles had on a 1972 audience. More than any other TV movie I've ever seen, I think Gargoyles should be remade today with a big-screen release, and Winston should recreate his creature suits with modern makeup technology. Although it is just a minor cult film, Gargoyles has the potential to be so much more... Just a thought.
