Old school effects

The original 'Ghostbusters' from 1984 was a visual spectacle and became renowned for its excellent practical effects. 

Luckily, despite the huge advancements in computer-generated visual effects, Dan Aykroyd has emphasised that the new movie will still retain the magic from the original. 

He said: "We've never done this to Manhattan before. There's a historical base to it that's quite beautiful. We took full advantage of CGI technology but we also, where we could, kept old school effects alive."
