I just read the review for Cursed unrated and there is no mention of a commentary by craven. i know that he said that he would never work with dimension again but all the specs that i read said the dvd would include a commentary. was this pulled or did it just not happen?

I bet it never happened. For Craven and Williamson to record a commentary, they would've had to view a final cut of the film. I don't think a final cut was decided on until after both left the project because Dimension kept screwing them over.
