“You never know in this business how long something is going to last” marvels Dan Aykroyd. Indeed some thirty-five years after its premiere, the surprise hit film Ghostbusters continues to enchant fans. Cleanin’ Up the Town is the definitive behind-the-scenes look at the creative process that brought the film to life, including a deep dive into the visual effects which were far ahead of their time.

Touching on everything from the casting process to the ginormous Stay Puff Marshmallow Man, it’s clear that those involved look back in fondness on the production. Twelve years in the making, and featuring interviews with Sigourney Weaver, Dan Aykroyd, director Ivan Reitman and the late great Harold Ramis, this is a must see for any Ghostbusters fan.

The screening on Tuesday the 14th of January was followed by a filmmaker Q&A.
