Actress Angelina Jolie, who played a tough-chick adventurer in the movie “Lara Croft: Tomb Raider,” is taking on a new role: eco-crusader. She has pledged to donate at least $1.3 million over the next few years to establish a wildlife sanctuary in northwest Cambodia, a region that until five years ago was controlled by remnants of the brutal Khmer Rouge regime. Known as the “100 Elephants Forest,” the pristine area is thought to be home to Cambodia’s last remaining wild elephants and tigers. A portion of Jolie’s donation will also go to help war veterans and amputees in the conflict-ravaged nation. Jolie fell in love with Cambodia while filming “Tomb Raider” there in 2000.
