Lettre de Sibérie

I saw this movie in college in the late 80's and loved it.

I also became a great Marker fan as a result thereof, but cannot find this movie anywhere. Does anyone know if it is available anywhere in any format?

This movie is a great spoof on the documentary process.

There are several websites that discuss this movie. One great scene wherein the same footage is played three times once with a pro soviet voice over once with a neutral one and again with an anti-soviet voice over. It skips from documentary into cartoon with a song in the background. Great film.
