The 2016 reboot of Ghostbusters was, by any metric you care to measure against, a failure.
It suffered middling reviews, an audience that didn't seem to want it, and an underwhelming box office to boot. In fact, after two weeks at the box office, it hadn't even made back its production budget - never mind the combined budget of production and marketing that went with it.
Against a production budget of $144 million, Ghostbusters made just $229.1 million worldwide and it's now well into the home market. This point wasn't lost on Dan Aykroyd, who served as an executive producer on both the reboot and the original as well as starring in both as well.
In an interview with Channel 4's Sunday Brunch, Aykroyd didn't pull his punches on where the fault lay with Ghostbusters. In his mind, it was squarely Paul Feig's fault. According to Aykroyd, Feig "spent too much on it and he didn’t shoot scenes we suggested to him. Several scenes that were going to be needed, he said, ‘No, we don’t need them.’ And then we tested the movie and they needed them, and he had to go back - about $30 to $40 million in reshoots."
However, according to a source who spoke to THR, said reshoots only cost around $3 million, and that Feig's relationship with Sony hasn't been damaged as Aykroyd intimated. As for Feig's relationship with Sony, he's been announced as directing a sequel to 2013's The Heat, but the film has been put on hold as Sandra Bullock just isn't up for it.
Other than that, Feig has no other projects listed on IMDb. THR's source, however, says that Feig's relationship with Sony was "incredible", so there's that to contend with as well. For his part, Aykroyd said that he "was really happy with the movie," but added that it simply cost too much and doubted that a sequel would happen.
Paul Feig hasn't publicly commented on Aykroyd's comments as of writing.
