19. The Force Awakens.
To shoot the scenes that take place on Rey’s home planet of Jakku, the cast and crew of Star Wars: The Force Awakens spent the first part of the film’s production in the blazing desert heat of Abu Dhabi. Actors Daisy Ridley and John Boyega trained on treadmills for all the running they’d have to do, but that didn’t prepare them for the added challenge of running on sand. Ridley said running on the combination of hard and soft sand was killer on the legs, and she was actually thankful for the shots that included explosions, because that usually meant fewer takes.
