 Principal photography began at Leavesden on October 1, 2012. The Los Angeles Times said on the second day, Liman "demanded a total reshoot of everything filmed on Day 1", which concerned producers. Filming on the beach set was scheduled to last two weeks, but extended to nearly three months due to what the Los Angeles Times called "the director's self-described' workshop-y ' filming style". Filming also took place in Trafalgar Square in London on November 24, 2012. The square was closed to the public, and tanks were brought in to film the action scenes. A former army base in the village of Barton Stacey in Hampshire, was also used as a filming location for two weeks.
