Return to Treasure Island is a 1986 Disney HTV TV series, starring Brian Blessed as Long John Silver, Christopher Guard as Jim Hawkins and Kenneth Colley as Ben Gunn.
His mother has laid on a surprise party, including as guests his old friends, Squire Trelawney, Dr Livesey, Captain Smollett and Ben Gunn.
Trelawney has been communicating with Jim Hawkins during his time at Oxford, and has appointed him agent to his plantations in Jamaica because of their failure to make any profits in the last year.
A search of the area reveals nothing, but later that night Silver appears in Jim's bedroom and demands the map of Treasure Island.
Hawkins thinks it's worthless, but Silver believes that a hoard of precious stones is still buried on the island, worth four times the gold previously found.
On board, they meet Dutchman Hans Van Der Brecken, Reverend Morgan and the beautiful Isabella, daughter of the Grandee of Spain.
He then persuades the crew and other captives to commit mutiny and they take the ship, only to find that Hawkins and Van Der Brecken are against them.
Silver takes Isabella hostage and confiscates a long boat with Hawkins, Van Der Brecken, and Morgan on board and they row to safety.
The final close-ups of Long John Silver rowing away from Jim Hawkins' ship and revealing that he had stolen all the diamonds from the treasure casket (inside a secret compartment of his crutch) were filmed on the roof of HTV's Pontcanna Studio (since demolished) in Cardiff.
