Did you know that classic film Casablanca  was based on an unproduced play titled Everybody Comes to Rick’s? by Murray Burnett and Joan Alison?; or that film Moonlight  was based on another unproduced play titled Moonlight Black Boys Look Blue by Tarell Alvin McCraney?

I previously reviewed such plays-turned-films as Prelude to a Kiss , Carnage , It’s Only The End of the World , Marjorie Prime  and Una , and other notable films in this category include Seventh Heaven , Brief Encounter , Steel Magnolias , Glengarry Glen Ross , Meet Joe Black , Closer , Doubt  and August: Osage County .
