I rented the blu ray from Blockbuster. Was looking forward to listening to the director's commentary, but there isn't any as far as I can tell. "Special Features" only has previews for other Lionsgate films and a bookmarks section. I brought up the audio options and English was the only audio track listed. Is the commentary on the regular DVD and not the blu ray?
Most rental companies (Blockbuster, Netflix, Redbox, etc.) get "Rental Only" copies of many DVD/Blu-Ray releases, and they'll have some bare-bones features, but for the most part, they will ignore the special features, because if you like the rented film, they're going to want you to buy it. It's all about the bucks.
