The James Bond movie franchise is now 50 years old — a birthday featured prominently in the film’s promotional materials, yet “Skyfall” injects the character and the franchise with renewed attitude and purpose. It’s a film that pays homage to Bond’s past, while also plotting a course for the future. The movie opens with a thrilling, extended action sequence which results in Bond (Daniel Craig) being shot by a fellow MI6 agent (Naomie Harris).
