’88 (Proof of Concept)’ is a Justin Berti movie that was released a few years ago. I’ve been hearing that it is available to watch on Amazon Prime. After some investigation found it’s listed on Amazon Prime USA, but not Amazon Prime UK at this time. It’s listed under the title ’88’. If you are interested in watching Justin in this, then please check Amazon Prime in your country, if you live outside USA, to check if it’s available.
