Why It Was Cancelled
- Plans for a Ghostbusters shared universe, as well as the sequel were cancelled due to the controversy and box office failure of the first Ghostbusters.
- Despite receiving positive mix reviews from critics, the film was panned by audiences and fans of the original films.
- Marketing for the first film was poor and the film failed to meet the expectations of being a hit.
- The box office failure of the first film lead to Sony losing $70 to $75 million and a $1 billion letdown in 2017, which meant that there was no likely chance for a sequel.
- Director Paul Feig didn't handle the criticism properly from fans of the original films.
- Paul also spent too much money on marketing and advertising and didn't pay attention to Sony's recommendations for using the budget money and Dan Aykroyd's rules on making the film. In a June 2017 interview, Dan told the interviewer about Paul's financial actions and added that Paul would not be back on the Sony lot after spending too much money on marketing and not enough on the budget. 
- The sequel was permanently cancelled following the poor performance of the first film, which later resulted in Sony losing $70 to $75 million (mentioned earlier). Despite the cancellation, Paul Feig still expresses interest in doing the sequel.
- The first film is stand-alone.
- A fully animated film fell into focus shortly after the 2016 movie was released. It was also going to be a tie-in with the 2016 movie.
- The animated film was also shortly cancelled as Sony decided to move forward with the upcoming film Ghostbusters: Afterlife.
- Sony went on to continue the original franchise instead of the reboot franchise with a third film titled Ghostbusters: Afterlife set to be released in 2021 with Jason Reitman, son of original Ghostbusters director Ivan Reitman at the helm while Ivan will be producer respectively. The film will star most of the original cast including Dan Aykroyd, Bill Murray, Ernie Hudson, Sigourney Weaver and Annie Potts reprising their roles from the first two films respectively and will star new cast members and will be a direct sequel to the original films thus ignoring the events of the reboot film.
