"Jack-O" was scripted by my good friend Brad Linaweaver, so I'm prejudiced in its favour. Low-budget film-maker Fred Olen Ray had a few minutes of footage of John Carradine sitting in a forest at night, and a bit more footage of Cameron Mitchell staring into a camera and telling a spooky story. Ray challenged Linaweaver to write a feature-length script using these snippets of footage. Carradine and Mitchell appear VERY briefly in "Jack-O", and not together.
"Jack-O" is a bog-standard spookfest. Jack-O-Lantern is a homicidal maniac who died in arcane circumstances but who still comes back for one night every year: guess which night. Yes, Hallowe'en. The crucial (dual) role in this film is a small boy in modern times who's related to Jack-O's first victim (also a small boy) from more than a century earlier on. When I saw that the child actor cast in these roles (Ryan Latshaw) is the son of the film's director (Steve Latshaw), I expected a vanity production. But young Ryan is actually a decent actor: in this film at least, his performance is better than his dad's directing.
I always expect zero production values in a film like this, so I was pleasantly astounded by the realistic 19th-century prologue. Brad told me that this was filmed in an historic village in Florida. Unfortunately, the first few minutes of the film look much, much better than anything afterwards.
There are several very attractive actresses in this film, notably scream queen Linnea Quigley as the heroine, and Catherine Walsh as a "bad girl" who MIGHT have supernatural abilities. Untalented Helen Keeling is attractive, but she speaks her dialogue with one of the most bizarre accents I've ever heard.
There are some REALLY grotty special effects: notably the lightning (why didn't they use a stock shot?) and the scene in which one character gets electrocuted. I've seen more realistic electrocutions in Tex Avery cartoons. The post-dubbing of the soundtrack is worse than it really needs to be for this low budget.
"Jack-O" isn't very good, but it isn't nearly bad enough to be one of those Ed Wood-ish camp classics. I strongly recommend it as a study aid for those who want to learn "Bowfinger"-style film-making techniques. And some of the actresses are very watchable. Otherwise, "Jack-O" is a Joke-O. For thrills and chills, look elsewhere.
