I saw this years ago when I first bought Total Recall. I forgot how funny it is. Most commentaries give us some insight into the making of the film, what the characters are thinking, what the film is trying to say, etc.
Ahnuld just describes what is going on. Usually he starts off a sign by saying "Dis is a really great scene," and then he describes that it's great because he is disguised as an old fat woman or because the Johnny Cab doesn't understand him.
Hilarious.
I guess there is no need to do a Descriptive Video Track for the blind. Ahnuld's commentary is good enough.
