Sergeant Ryker is a 1963 drama–war film directed by Buzz Kulik and starring Lee Marvin, Bradford Dillman and Peter Graves that was initially shown on television but released theatrically five years later in 1968. The film was originally broadcast on television as "The Case Against Paul Ryker", a 1963 two-part episode of Kraft Suspense Theatre. It was released as a feature film in 1968 to capitalize on Marvin's popularity from The Dirty Dozen. Its second run paired it as a double feature with Counterpoint (1968) starring Charlton Heston.
