Peter Pan, his fellow characters, and the setting of Neverland have appeared in many works since the original books and 1904 play by J. M. Barrie. The earliest were the stage productions of the play, and an adaptation to silent film, done with Barrie's involvement and personal approval. Later works were authorised by Great Ormond Street Hospital, to which Barrie gave the rights to the Peter Pan works; these include adaptations of the main story in both animated and live-action films, musical stage productions, and a sequel novel. In addition, there have been numerous uses of Barrie's characters, settings, and storylines which challenged or took advantage of the changing copyright status of these elements, including reinterpretations, sequels, prequels, and spin-offs in a variety of media, including film, television series, and books.
Adaptations of Peter Pan for public performance have a unique status in UK copyright law: Great Ormond Street Hospital has the right to receive royalties in perpetuity under specific provisions in the Copyright, Designs and Patents Act 1988.
When dramatised, the character of Peter has usually been played by an adult woman. For boys' roles to be played by women is a convention of the pantomime tradition that was popular when the play was first produced, and was necessitated by laws restricting the use of child actors for evening performances. Later adaptations have often followed this example, for reasons that include tradition, the performance demands of the role, and the marketing advantages of "star" actresses. The roles of Captain Hook and George Darling happened to be played by the same actor in the original production, a tradition which has sometimes been continued in later dramatic adaptations.
