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? Many a great film first originated in a play, and because of this origin, these films often rely much on performances and have certain “intimacy” to them not found in other films. 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 . Below are ten great films that first originated in plays (excluding Shakespearean adaptations).

Play: Trämålning (Wood Painting)  by Ingmar Bergman
This well-known masterpiece of a film by Ingmar Bergman stems from a one-act play by Bergman himself. He wrote a play titled Trämålning (Wood Painting) and it was initially supposed to be a play to be performed by students. In the story, the country is suffering because of the Black Death pandemic and a young Knight with his Squire have just returned from the Crusades. The land is in panic, and, unwittingly, the Knight joins a wagon of travelling performers. Death is also their follower, challenging the Knight to a play of chess. What will be the outcome? Philosophical, visually-striking and full of symbolism, The Seventh Seal is an uncanny portrayal of the Middle Ages and an iconic film in the history of cinema.Read more
