Mary Poppins Returns development hell since the release of the 1964 film. Walt Disney attempted to produce a sequel a year subsequent to the film's release, but was rejected by author P. L. Travers, who had openly dismissed Disney's film adaptation. In the late 1980s, then-chairman of Walt Disney Studios Jeffrey Katzenberg and vice-president of live-action production Martin Kaplan approached Travers with the idea of a sequel set years after the first film, with the Banks children now as adults and an older Mary Poppins with Julie Andrews reprising the role. Travers again rejected the proposed concept with the exception of Andrews' return.
Mary Poppins film is not a reboot or remake of the original 1964 film, Mary Poppins revisits the Banks children from the first film. It is loosely based on the other seven "Mary Poppins" books by Travers, and expands beyond them. Emily Blunt stars as Mary Poppins, alongside Lin-Manuel Miranda in the role of Jack, a similar character to Dick Van Dyke's Bert from the first film. It was announced on 31 May 2016 that the film is titled "Mary Poppins Returns" and takes place in Depression-era London, 20 years after the original film. Emily Mortimer and Ben Whishaw play grown up
