From the start of "World War Z 2" (2017, Timeline-ATTF).
What if the movie "World War Z" was a successful success while the film would have a sequel titled "World War Z 2" was still being released on June 9, 2017?
According to a report in the Los Angeles Times in January 2012, at that time Marc Forster and Paramount Pictures both viewed "World War Z as a trilogy that would have the grounded, gun-metal realism of, say, Damon's Jason Bourne series tethered to the unsettling end-times vibe of AMC's The Walking Dead." Plans for future installments were shelved for a time due to the film's production troubles, but in June 2013, after the successful opening of the film, Paramount announced it was moving ahead with a sequel. In December, it was reported that J. A. Bayona had been chosen to direct the film, and in May 2014 Steven Knight was set to write the script. In May 2015, it was announced the sequel would be released on June 9, 2017, but in January 2016 Paramount announced director Bayona had left the project due to other commitments.
Variety reported in August 2016 that the sequel was not yet in production, but David Fincher had entered negotiations to be the director, and in April 2017 it was reported Fincher was close to a deal to sign on. On February 8, 2017, Paramount announced the sequel had still not started filming and would not be released until 2018, or possibly even 2019.
Fincher was confirmed by Paramount as the director of the sequel in June 2017, with Brad Pitt to play again the role of Gerry Lane. Filming was slated to start in fall of 2018, though this later changed due to Fincher's involvement in the television series Mindhunter. In October 2018, producer Dede Gardner confirmed the sequel would begin filming in June 2019, and there were several months of pre-production and staffing for principal photography in five countries, but, in February 2019, the film was cancelled. A source quoted by The Hollywood Reporter said the Chinese government's ban on films featuring zombies or ghosts was the single major reason that Paramount canceled the sequel.
