Treasure Island is a 1977 television adaptation of Robert Louis Stevensons famous 1883 novel. It was filmed in 1977 on location in Plymouth and Dartmouth Devon, and in Corsica, and also at BBC Television Centre at Wood Lane, London.
While the director, Michael E. Briant, has clearly made sure that all the characters are much more strongly defined on screen than they are in the novel, and has cast most of the great TV character actors of the 70s, Alfred Burke is a quite astonishing Sea Cook slick, violent, cunning, and dangerously plausible. The characterisation bears comparison with that of Robert Newton.
