The mystery movie Alex just filmed is called The Strange Ones. http://paparazimagazine.com/index.php/2016/08/29/alex-pettyfer-to-star-in-the-strange-ones-exclusive/
Alex is going to be a co exec producer for an hbo film starring J Lo. I wonder if this is the film he was talking about cos that could also mean he is starring in it?
I can’t seem to find any article about it. He said he will start filming soon.
