Das Kovak Labyrinth

I'm not sure I've seen the 'Gloomy Sunday' reference explained here. 'Gloomy Sunday' was written by Hungarian composer Rezső Seress in 1933. The song is legendary for (allegedly) causing people to commit suicide after hearing it. Check out Wikipedia (search 'Gloomy Sunday') for the very interesting background on the song.

As for the movie, I really thought it was first-rate. I found it at the video store, and got it thinking it might at least entertain me. It did more than that - the plot had me hooked from the first five minutes on.

A "Kovak Box" is explained in the movie, but that itself is a reference to the "Skinner Box" of B.F. Skinner. This article, which comes from Snopes.com provides some very interesting background tidbits to the movie - you will recognize where certain plot elements come from - http://www.snopes.com/science/skinner.asp.

If you like movies with a lot of intrigue, this is a great one to rent.
