Feig understands the backlash from diehard fans of the original two movies who are unhappy he has rebooted the franchise with an all-female spook fighting squad.

Feig admits if he wasn't directly involved in the project he would be concerned about Melissa McCarthy, Kristen Wiig, Kate McKinnon and Leslie Jones taking over from Bill Murray, Dan Aykroyd, Harold Ramis and Ernie Hudson.

He said: "I think the only frustrating part, and I find it tends to be the thing with the internet that we didn't have before, is people feel more ownership over everything, they are getting so much information they think they can pre-judge it. You get comments like, 'This movie's terrible,' but it's like, 'You didn't see the movie!' "What I understand is there's so much passion towards these movies and people are rightfully nervous. If I wasn't doing it I would be just as nervous as everyone else is. But again, all you can say it, judge it on its own merits."

In his younger years, Feig always hoped he'd one day make a film similar to 'Ghostbusters' and the irony he's responsible for the reboot isn't lost on him.

Speaking to website HeyUGuys, he said: "I saw it in college and I'd never seen a comedy like that before, that had the scope and scares but was also hilarious, it always stuck with me, I always wanted to make a movie like that and then I ended up making that same movie."
