APOCALYPSE wow! This is the first glimpse inside the south Essex location where Brad Pitt filmed scenes for his blockbuster World War Z.

The Hollywood A-lister spent two weeks on set in East Hanningfield, shooting scenes for the apocalyptic zombie horror, which is on in cinemas now.

Because of tight security it is only now details about the shoot can be made public, and snippets like what Brad used to eat for breakfast and how he was helicoptered into Essex each day, can be revealed.

Filming took place at the Essex and Suffolk Water treatment works, in East Hanningfield, and saw more than 100 crew including 50-yearold Brad and director Marc Forster on site every day.

A now redundant part of the treatment works building – the vertical flow tanks – was transformed into Camp Humphreys, a dank South Korean military base and prison, for pivotal scenes in the film.

Gary Banks, treatment operations manager for Essex and Suffolk Water said: “We were thrilled that Hanningfield works was selected as a location for World War Z.

“This building is quite striking and makes interesting backdrop for filming. We’ve been marketing it as a film location for several years now.

“World War Z was the biggest production we’ve ever had. Our 300 employees were fantastic while filming was taking place – they really respected the privacy of the actors.”

Gary added: “I went to see the film on the opening night and it was amazing to finally see it. I’d say thebits that were filmedhere appear in about six minutes of the film.”

One of the most famous movie stars on the planet, Brad kept “himself to himself”.

Gary said: “He seemed like a normal, nice bloke who was dedicated to his job.

“He’d be flown in by private helicopter to an airfield about half-an-hour away every morning and then be driven by a chauffeur to the set.

“I sort of bumped into him by accident as he was packing up his stuff one day and he said hello.

“Unfortunately, Angelina didn’t turn up.I’ve been getting that question a lot!

“Of course it was really exciting for staff here to have him filming.”
