More than anyone else, it was the late Paul Walker – the handsome, blue-eyed star of Universal’s $2 billion Fast & Furious mega-franchise – whose presence was most felt at that film’s world premiere at South by Southwest late Sunday, early Monday local time. Walker, who plays FBI agent Brian O’Connor in all but one of the films, was killed in a car accident on Nov. 30th, 2013, along with his friend and financial advisor, Roger Rodas , who was driving the vehicle.
