According to original 'Ghostbusters' star Dan Aykroyd, the sci-fi comedy reboot's director Paul Feig is the reason why the film most likely will not get a sequel. Aykroyd, who served as executive producer on the movie, said in a recent interview that he believes Feig allowed the film?s costs to get out of hand with reshoots. This, Aykroyd went on to say, meant a lower return on investment for Sony Pictures at the box office.
