This movie recently appeared as part of a collection of 8 movies retailing for about $4 (used). So while it's not good, the real question perhaps is, is it worth 50 cents? Well, I'd say Simone "Death Race 2000" Griffeth's generous nude scenes are definitely worth 49 cents. But it's that extra penny that's the real sticking point.
In the movie's favor, it was pretty early entry into the "erotic thriller" genre, a genre which has only gotten worse and worse with each passing year, and it was obviously inspired by "Body Heat", perhaps the ONLY classic erotic thriller. Interestingly, the gender roles are completely reversed here--it's Simone Griffeth's character, an American woman married to an obnoxious British industrialist, who is the naive prey, while the man, a handsome American thief and con artist, is the seductive predator (a homme fatale?). The overall plot though occupies that gray area between uniquely bizarre and completely non-sensical. It's also interesting that it is set in Britain, and aside from the two leads, features an entirely British cast. After all, the Brits are not exactly known for erotic thrillers (or for anything erotic, for that matter). Of course, that doesn't make the movie good or bad, but it is interesting.
But is any of this really worth that extra penny? I don't know--flip a coin.
