No commentary
I bought the Herzog/Kinski DVD box set and Woyzeck has no commentary feature - bit disappointing as Herzog is usually very entertaining and informative.
shareHerzog first recorded the English audiocommentaries (the US + UK DVDs were released first) and later on recorded the German commentaries for most of his films.
There is no English commentary for "Woyzeck" but an audio commentary (without the film in the background) for the German release.
"Cobra Verde" has an entire feature length commentary on the English DVDs and a shorter commentary without the movie playing in the background (like the German "Woyzeck" one).
Also there is an audio commentary on the German "Invincible" DVD but not featured on the American release:
