In 1994, director Frank Darabont made The Shawshank Redemption, a movie that he dedicated to a man named Allen Greene, who was a major reason why the Stephen King adaptation happened in the first place. The Shawshank Redemption is an iconic drama film starring Tim Robbins as Shawshank’s Andy Dufresne, a man who is wrongfully sent to prison for killing his wife and her lover, and while there, forms a bond with other prisoners, including a man named Red, played by Morgan Freeman. The movie is based on a 1982 novella written by horror author Stephen King.
