[8] The film was shot in CinemaScope and color at Sydney's Pagewood Studios and the same company went on to make The Adventures of Long John Silver, a 26-episode TV series with the same actors.

Long John suggests to Mendoza that he leave Elizabeth on shore and lure the governor's warships away in order to sack the king's warehouses.

As Mendoza carries out the plan, Long John finds that Jim possesses the pirate medallion indicating the second treasure's location.

Once on Treasure Island, Long John and his men take shelter in the stockade from Israel Hands, who had survived Jim's shot some time ago, but is blind.

Soon, Mendoza's men arrive, and Israel offers to side with Long John in return for a passage to Cornwall and vengeance against Jim.

Long John returns to Portobello as a rich citizen and dines with the Governor, during which it is implied that Silver received a pardon for his past crimes for the role he played in saving his daughter's life, and for a "generous donation to Government House" that served to "arm the harbor against pirates".

Walt Disney's film of Treasure Island (1950), starring Robert Newton as Long John Silver, had been very successful at the box office.

Byron Haskin alleged that producer Joseph Kaufman ran out of money during production, making shooting extremely difficult.

[13] Byron Haskin had experience working with Australians on His Majesty O'Keefe (1953) and cast several actors from that film, including Grant Taylor, Muriel Steinbeck, and Guy Doleman.

Doleman was selected to play Israel Hands but refused to grow a beard and wear contact lenses which were required for the part.

The filmmakers also constructed a galleon on a barge at Botany Bay, and filmed a sea battle between six foot model ships in Port Hacking.

[24] Kaufman took out an option on Pagewood Studios for two more years and announced plans to make other films in Australia including Come Away, Pearler, from the novel by Colin Simpson.

The film and its star Robert Newton were referenced several times in the UK TV comedy series Hancock's Half Hour (1956–1961).
