The poor audio quality of Orson Welles' dialogue was apparently due to his recording all his lines in one night in Rome whilst drinking white wine. In 1979, Welles claimed his voice in the film was re-dubbed by another actor. This was true for some versions of the film.

Orson Welles was originally supposed to play Silver in a film version of "Treasure Island" in 1964 after he had finished filming Falstaff (1965), but filming was abandoned after only a few days due to lack of money. However, he remained contractually bound to the role and was, therefore, cast in this 1972 version.

Orson Welles did not like the rewrites to his script, so he asked to be billed as "O W Jeeves" in the opening credits.

Director John Hough confirmed in an interview that he was the sole director of this film, and Andrea Bianchi (credited under the alias 'Andrew White') was only listed on European versions of the film for tax reasons, as this film was a European co-production. Bianchi was actually the second unit director on the film, notably working on the opening 'Admiral Benbow Inn' scenes of the film (set in England but shot in Italy), filmed on location around the Monte Gelato Falls near Rome.

In some versions Orson Welles is dubbed by Robert Rietty.
