Screener's are sent to reviewers or video stores before they hit retail.. I am not sure about this one, but sometimes you get grayscaled parts, and security warnings.. But it is the full movie..

I know you don't smoke weed. I know this. But I'm gonna git you high today. 'cause it's Friday, you ain't got no job, and you ain't got shit to do!
