My favorite movie is shawshank redemption, it was released in 1994. it was based on a novel by Steven King. It’s a movie about Andy Dufresne (played by Tim Robbins), who is sentenced to two life terms in prison for the murders of his wife and her lover and is jailed in a tough prison. However, only Andy knows he didn’t commit the crimes. While there, he forms a friendship with Red (Morgan Freeman), experiences brutality of prison life, adapts, helps the Warden, all in 19 years. Then he escapes the prison by digging the wall with a hammer which was given to him by Red. When he finished digging up he escaped.
Also Tim Robbins had a program, where he had acting classes in prison, and he told that none of the prisoners who finished his class returned to prison.
