Death Drums Along the River was the come-on American title for this 1963 remake of 1935's Sanders of the River. Both films were loosely based on a very popular Edgar Wallace novel. Richard Todd assumes the leading role of Harry Sanders (originally R. G. Sanders), a British police investigator working in Africa. While counting the clues in a hospital murder case, Sanders is led to hidden diamond mine. The patronizing racial attitudes prevalent in the first Sanders of the River have been muted and altered out of respect for the ever-changing Africa of the 1960s. Sanders did well enough to inspire a 1964 sequel, Coast of Skeletons. ~ Hal Erickson, Rovi
