Shooting also took place in Iceland, where Nolan had previously filmed scenes for Batman Begins (2005). It was chosen to represent two extraterrestrial planets: one covered in ice, and the other in water. The crew transported mock spaceships weighing about 10,000 pounds (4,500 kg). They spent two weeks shooting there, during which a crew of about 350 people, including 130 locals, worked on the film. Locations included the Svínafellsjökull glacier and the town of Klaustur. While filming a water scene in Iceland, Hathaway almost suffered from hypothermia because her dry suit had not been properly secured.
