Coast of Skeletons

Coast of Skeletons is a 1965 adventure film, directed by Robert Lynn and starring Richard Todd and Dale Robertson. It is a sequel to the 1963 film Death Drums Along the River, and just as that film, it uses the characters from Edgar Wallace's 1911 novel Sanders of the River and Zoltán Korda's 1935 film based on the novel, but placed in a totally different story. Coast of Skeletons was released in Germany as Sanders und das Schiff des Todes/ Sanders and the Ship of Death.
