In June 2018, it was reported that Jonathan Kasdan had replaced Koepp as scriptwriter, and that the film would miss its 2020 release date. Shortly thereafter, Disney postponed the film's release date to July 9, 2021. A few months later, Marshall stated, "I dunno if you'd call it a writers room, but a lot of people that we trust pitch ideas and things." In May 2019, it was reported that Kasdan had written his script from scratch, but that his work was now being replaced by Dan Fogelman, whose screenplay used "an entirely different premise". Two months later, Ford said that the film "should be starting to shoot sometime next year". Later reports narrowed the beginning of filming down to April 2020, suggesting principal photography was to take place at the Iver-based Pinewood Studios. Speaking in September 2019, Koepp said that he was working on the project again, and that they had "got a good idea this time".
