While World War Z wasn’t the most effective zombie movie of 2013, it’s opening action sequence was definitely worth the price of admission. The film went from quiet to chaotic in one scene featuring the terrifying zombie outbreak in Philadelphia. It’s just that after that scene, the film really loses steam and its gumption. In the above VFX video, we see how the filmmakers and visual effects artists pulled off a number of the film’s action scenes.
World War Z‘s first action sequence takes place in Philadelphia, but it was actually shot in Glasgow, Scotland. According to CBM, Cinesite VFX supervisor Matt Johnson and VFX photographer Aviv Yaron took a large array of photos of buildings around the Pennsylvania city to digitally match them with the Glasgow setting. The effects looked really believable and go to show how well CGI can be used when blended with practical effects.
