* FakeScot:
** The American Creator/JohnnyDepp as James M Barrie.
** In the Broadway musical, James M Barrie is often played by American actors as well.
* TheShelfOfMovieLanguishment: The movie was filmed in 2002 but wasn't released until 2004 as Miramax didn't want the film to open close to ''Film/PeterPan''. In a case of Administrivia/TropesAreNotBad, the delay helped get the film a number of Oscar nominations (including Best Picture).
* ThrowItIn: At the ClapYourHandsIfYouBelieve part, the uptight Emma starts clapping fervently. The children were shocked in response, since Creator/JulieChristie wasn't supposed to.
* WagTheDirector: The original script, however, called for Creator/DustinHoffman to be dressed in Captain Hook's costume as he playfully read the Playbill. Upon reading that scene, Dustin said to Creator/MarcForster, "I'm not being Film/{{Hook}} again!" The script was then changed.
* WhatCouldHaveBeen: Creator/JimCarrey was considered for Creator/JMBarrie.
* It is an urban legend that Barrie asked for 25 seats to be held for children from a nearby Orphans' Asylum, thinking that if adults didn't understand the play, they could take their cues from the kids' reactions. It seems that Barrie considered this but decided it wasn't necessary, and the audience did get it, that this was a play ''for'' adults to ''remember'' being kids, as well as a play ''for'' kids.
* Barrie asked Peter Davies what was the part he liked best. Young Master Davies replied: "the best part was tearing up the programme and dropping the bits on people's heads." Barrie was delighted.
