Andrew “Andy” Dufresne is a wrongfully-accused prisoner and the main protagonist in Rita Hayworth and Shawshank Redemption, as well as its film adaptation, where he was played by Tim Robbins. Andy is portrayed as intelligent, quiet and very honest, although very witty and personable when he wants to be. This is a great contrast to the other inmates, who are hardened criminals.
Andy was a young, successful banker who was wrongly convicted of murdering his wife and her lover based on circumstantial evidence. Andy was incarcerated at Shawshank Prison in 1948, where he wore the prisoner number 81433-SHNK. Like almost everyone else in Shawshank, Dufresne insists on his innocence, and nobody believes him.
