Was P.L. Travers racist of Americans?
Travers eventually agreed to sell the stage rights after being approached by London theatre producer Cameron Mackintosh. She acquiesced on the condition (expressed in her will) that only English-born writers – and no Americans, particularly anyone involved with the film production – were to be directly involved in the creative process of the stage musical.[7]
^ I don't think her hate towards the film caused her to dislike Americans but i think she didn't like Americans before coming to the US so it's not explained why she hated Americans so much, After seeing Saving Mr Banks and doing some research it seems she wasn't very fond of Americans so their must've been a reason why she hated anyone born American.
