Hell River, also known as Partisans (Serbo-Croatian: Partizani / Партизани) and The Last Guerilla, is a 1974 Yugoslav partisan film starring Rod Taylor as a Yugoslav raised in America who returns home to fight the Germans as a Partisan in World War II. Adam West plays a German officer.

The film was shot on location in Yugoslavia, and claims to be based on a true story. There are several versions, including an original three-hour cut made for Yugoslavian television, and a feature-length version for the American market. Rod Taylor was involved in rewriting and shooting some additional scenes during post production.
