Lena Headey

Bear takes Lena on the ride of her life as they paramotor deep into the remote Spanish wilderness. Continuing on foot, they traverse a towering, razor-thin ridge before a dead-end forces a harrowing rappel. After securing a dinner of bone marrow from a goat carcass, the two must cross a lake using a makeshift raft as an unexpected storm wreaks havoc. As they battle the elements, Lena grants us exclusive details of life on "Game of Thrones," her rise to stardom, and her battle to overcome depression.
