Movie about L.A. Boarding School in the 1980s', I think based on a story

Hello,



Can anyone on here help me, please ? I'm trying to look for a Movie, I can't remember the title, but It's coming out in 2017 ? or later this year. It's a Movie about a Boys' Private School set in the 1980s' in Los Angeles.



I can't even remember who's going to be in the Movie.



With Thanks




Michael
