I'm a big fan of The Lost Skeleton of Cadavra. This movie definitely falls short of that one, at least on the first viewing, but still has its charm.
If you're unfamiliar with Larry Blamire's work, this film is a "tribute" to those classic 1940's murder mysteries. As with Skeleton, it's definitely a comedy, but not a full-blown parody film. The film is funny (arguably) because it's a bad 1940's movie, not because it's full of jokes. However, there are jokes there too.
The film succeeds in nailing a few stereotypes from the era. Some of the characters are very fun to watch (the high class British guy, the jungle guy, and the cook are among my favorites). Blamire also throws in some great jokes and a couple spoofs on movie conventions.
Unfortunately, this film doesn't work nearly as well as his other movies. First off, the genre isn't played with enough. Just because the murder mystery clichés are exposed doesn't mean they're funny. A prime example of this is the dialogue. Often the dialogue is clichéd, but not unbelievable. Unfortunately, it's done *just* serious enough to not be funny or clever. We're left feeling like there's nothing intentionally funny going on.
Blamire is clearly walking a thin line here: he's trying to make the film believable for the time AND funny for being of that time. Sometimes it works, sometimes it falls flat.
Another of the film's shortcomings is inconsistent characterization. Some of the characters are great, but a few are weak, annoying, or simply feel tacked-on (and not for the sake of being tacked-on).
Ultimately, this film falls short of both Lost Skeleton and its sequel. There are definite laughs to be had, and I suspect a second viewing will provide some new laughs, but overall this film feels lost between dedication to the genre and making fun of it.
