Treasure Island is a 1977 television adaptation of Robert Louis Stevenson’s famous 1883 novel. It was filmed in 1977 on location in Plymouth and Dartford, and in Corsica, and also at BBC Television Centre at Wood Lane, London. Jim Hawkins discovers a treasure map and embarks on a journey to find the treasure, but pirates led by Long John Silver have plans to take the treasure for themselves by way of mutiny. This four-episode adaptation by John Lucarotti, while particularly faithful to the original, adds an expanded narrative concerning the declining Daniel Hawkins, as well as clarifying Squire Trelawney's naiveté in trusting Blandly and Silver. This takes place in the first episode; Billy Bones tempts Jim's father into arranging a two-man treasure voyage, the corrupt shipping agent Ezra Blandly guesses their intentions and tips off Silver, who hoodwinks and then cruelly tortures the information out of a hapless alcoholic Mr Arrow. Billy Bones plans founder, and Hawkins snr catches pneumonia in the rain, which finishes him. Lucarotti's additions to the original provide useful backstory, and the pirate idiom is sufficiently well captured for these additions not to be too obvious.
