It’s hard to believe that it’s been 40 years since 1984 comedy classic Ghostbusters first barrelled onto our screens and introduced the world to the exciting realm of paranormal investigation and ghost catching. Featuring a star-studded cast that consisted of Bill Murray, Sigourney Weaver, Ernie Hudson, Dan Aykroyd and Harold Ramis to name just a few, the movie spawned a successful franchise spanning games, cartoons, comics, and even four other movies, the latest of which was released just this year.
