Weta Digital worked on the final, violent battle on Alcatraz Island in San Francsico between the X-Men and Magneto’s militant group; and the ‘Car-BQ,’ where Magneto is throwing cars and Pyro is lighting them on fire. Weta Digital used CityBot, the procedural city software developed on King Kong, and Lord of the Rings's Massive software to deliver the Alcatraz set, complete with Mutants en masse, fire, destruction and Wolverine’s ripping flesh.
