The movie consists of outtakes from other movies bolstered with some 'behind the scenes' stuff. It gives you an OK sample of what the studio is about. There are lots of cum shots, anal sex, and pretty good looking women.
The downside is that even though the outtakes are from different directors movies, they tend to have a very similar feel. The shots are obviously not spontaneous, they tend not to show the actual insertion (especially anal insertion, except for the 'Matador' series outtake). They just have a cookie cutter feel. The behind the scenes stuff is also weak, as it is mostly highly promotional, though really the video itself is a promotion for Private's other products.
The DVD does have some extras like still photos.
