Walt Disney Pictures announced the film in September 2015. Marshall was hired later that month, and Blunt and Miranda were cast in February 2016. Principal photography lasted from February to July 2017, and took place at Shepperton Studios in Surrey, England. Mary Poppins Returns held its world premiere at the Dolby Theatre in Los Angeles on November 29, 2018, and was released in the United States on December 19, 2018, making it one of the longest gaps between film sequels in history at 54 years.
The film received generally positive reviews from critics, who praised the acting (particularly by Blunt and Miranda), musical score, musical numbers, visuals, production values, and sense of nostalgia; although some critics found it derivative of the first film.[6] It was chosen by both the National Board of Review and American Film Institute as one of the top ten films of 2018 and received numerous award nominations, including four at the 76th Golden Globe Awards (including for Best Motion Picture – Musical or Comedy) and nine at the 24th Critics' Choice Awards as well an SAG Award nomination for Blunt at the 25th Screen Actors Guild Awards.
