Acting for Two: One of the few things that the film and the stage play have in common is that Captain Hook and Mr. Darling are both played by the same actor; in this case, it's Hans Conried.
Actor Allusion: Wendy shares a voice actress with Alice from Alice in Wonderland, and several scenes play this up. Her general personality resembles Alice in the first place, and her rambling to Peter when she first meets him seems to call back to how much of Alice in Wonderland is taken up of Alice talking to herself.
Peter: Girls talk too much.
Cross-Dressing Voices: Averted. In both movies, Peter is voiced by males: Bobby Driscoll in the first movie and Blayne Weaver in Return to Neverland. In fact, the Disney version was the first one to have a male play Peter's part rather than a female.
Development Hell: This was intended to be Disney's second theatrical film, but Walt didn't get the rights to it until 1939, when J.M. Barrie bequeathed the ones to his play to him. Then, he began developing the story and character designs, and intended it to be his fourth film. However, the onset of World War II put the brakes on this — along with several other films — and it became Disney's fourteenth entry in 1953. This also resulted in the movie appearing as an Early-Bird Cameo along with Alice in Wonderland as a storybook on the shelf at the very beginning of Pinocchio.
