a lot of that stuff had to fall away for the story to come together." Lindelof explained that there were inefficiencies in the script in relation to the shooting that started before the script was finalized, making the ending "abrupt and incoherent", and that the film was missing a large chunk of footage. He presented two options to executives, who ultimately chose to shoot 30 to 40 minutes of additional footage to change the ending. However, Lindelof, who also reworked Prometheus and co-wrote Star Trek Into Darkness, did not have time to script the new ending, so in July Paramount hired his Lost partner Drew Goddard to finish the work. Goddard later told Creative Screenwriting: "To me the big lesson of World War Z was that Paramount, Plan B and Brad Pitt simply said, 'Let's take the time to make this movie the best version of the movie before we put it on the screen for audience.' That doesn't happen a lot. A lot of times they just throw the movie out there and say, 'We'll make all our money opening weekend and then the movie will go away.' I came away from it thinking, 'Why don't we do this on more movies?'" The re-shoots, coupled with other overages, caused the film's budget to balloon to around $190 million, which shocked Paramount president Marc Evans. Several of the scenes shot in Budapest, including a large-scale battle with the zombies in Moscow's Red Square, were dropped from the final cut in order to water down the film's political undertones and steer it towards a more generally friendly summer blockbuster. The climactic battle scene in Russia, for which there was 12 minutes of footage, reportedly had Pitt's character fighting through zombies more like "a warrior hero" than "the sympathetic family man" of the earlier acts. The second-unit director, Simon Crane, said: "It wasn't character-driven anymore... [The filmmakers] really needed to think about what they wanted to do with the third act." Additional scenes were also filmed at the Pfizer building at Discovery Park in Sandwich, Kent, for scenes where Gerry tries to find a cure for the zombie pandemic. In March 2013, it was reported that Paramount changed a scene in the film, in which the characters speculate that the zombie outbreak originated in mainland China, in hopes of landing a distribution deal in the country.
