On March 20, 2017, it was announced that Robert Downey Jr. would star in The Voyage of Doctor Dolittle, a feature adaptation of The Voyages of Doctor Dolittle. In December 2017, Harry Collett and Jim Broadbent were cast. In February 2018, Antonio Banderas and Michael Sheen were cast in live action roles while Tom Holland, Emma Thompson, Ralph Fiennes, and Selena Gomez were cast to voice animals in the film including a tiger, bear, and a lioness. In March 2018, Kumail Nanjiani, Octavia Spencer, John Cena, Rami Malek, Craig Robinson, Marion Cotillard, Frances de la Tour and Carmen Ejogo joined the voice cast.
Principal production commenced mid-February in 2018. Live action scenes began filming in Kirkby Lonsdale, Cumbria in May 2018, with further location filming at South Forest, Windsor Great Park and on the Menai Suspension Bridge in North West Wales, in June 2018.
In April 2019, it was reported the film had undergone 21 days of re-shoots following poor test screenings. Director Jonathan Liebesman helped to oversee the filming alongside Gaghan while Chris McKay helped write new material, after it became clear from first cuts that the comedy and computer-generated elements of the film were not coming together as well as the producers had hoped.
In August 2019, it was reported that the film's title had been changed from The Voyage of Doctor Dolittle to simply Dolittle.
The film was originally going to be released on May 24, 2019, by Universal Pictures but was moved to April 12, 2019, to avoid competition with Star Wars: The Rise of Skywalker. It was later pushed back to January 17, 2020,  while The Rise of Skywalker was also pushed back to December 20, 2019.
