A rather mixed bag as it turns out, Private Castings shows us the initial interview which brought various Private starlets into the Biz, and then shows them doing their thing in a Private production (which is suitably plugged in the process). The effect is of two contrasting characters. If, on the one hand, the young woman in question seems very much into making porn and fucking on camera and generally exhibits an attractive personality, the effect is quite hot, showing it as it does a bit of the real person behind the sex-biz glitz. If, on the other hand, she seems to be making a mistake by entering the biz or doing it for any of the many, many really bad reasons, the effect is crashingly depressing, and the sex is (surprise, surprise) flat and drab.
