Just as the previous reviewer, I too went to see the movie as soon as I saw Klaus Kinsky in the thumbnail. The movie is basically a nice mix of Clue and a detective drama with a little suspense - kind of like the original House on Haunted Hill, but without the supernatural. For a 1960s movie it aged pretty well, and still holds its suspense - even though one could easily guess the main culprit, the number and variety of accomplices was quite surprising. The only thing I wasn't too excited about was music, which was very inappropriate to the mood in some scenes.

I was psyched when I saw Kinski's face on the thumbnail for this flick. Add Klaus Kinski to any b-movie and you've got your hands on some true drive in gold. Then all of a sudden they hit me with it. The socks literally flew off my feet when I realized that Klaus is playing a duel role! A double helping of the diminutive king of over-the-top acting, and very (and I mean badly) dubbed to boot. Add to all of the aforementioned, a soundtrack that punches you in the eardrums about every three minutes or so with a heaping helping of super hep spy jazz, and you just went platinum... you know man, real gone! Oh, and to top it all off, there's a killer with a really ineffective looking gauntlet wasting cast members right and left. With a paper thin plot that you'll more than likely have guessed by the end of the credit sequence, you shouldn't expect many real surprises, just B movie fun.
