"Treasure Island" was an international hit, and there were several other film projects involving Driscoll under discussion, but none materialized. For example, Haskin recalled in his memoirs that Disney, although interested in Robert Louis Stevenson's pirate story as a full-length cartoon, always planned to cast Driscoll as Mark Twain's Tom Sawyer. He was at the perfect age for the role, but because of a story rights ownership dispute with Hollywood producer David O. Selznick, who had previously produced the property in 1938, Disney ultimately had to cancel the entire project. Driscoll also was scheduled to portray a youthful follower of Robin Hood following "Treasure Island", again with Robert Newton, who would play Friar Tuck, but Driscoll's run-in with British immigration made this impossible.
