The script was developed over a long period:
Ivor Dean played Silver in the successful 1966 miniseries
Treasure Island and wanted to continue this with a sequel miniseries. Together with writer Robert S. Baker, he developed a story, but it had to be shelved after Dean’s death in 1974. It was ultimately adapted into this miniseries. 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. The tall ship
Kaskelot was used for the filming of the series. ==Music==
