 Never at ease with the handling of her property by Disney or the way she felt she had been treated, Travers never agreed to another Poppins/Disney adaptation.So fervent was Travers' dislike of the Disney adaptation and of the way she felt she had been treated during the production that when producer Cameron Mackintosh approached her about the stage musical in the 1990s, she acquiesced on the conditions that he use only English-born writers and that no one from the film production be directly involved.On December 19, 2018, Walt Disney Pictures released the film "Mary Poppins Returns".
