From IMDB:

Hollywood hunk Ben Affleck has likened the mania surrounding his on/off wedding to Jennifer Lopez to a car crash. The pair were due to marry in Santa Barbara, California in September, but the ceremony was canceled at the last minute after details were leaked to the press - amid an overwhelming flurry of media interest. Four months on, Affleck is able to reflect on the experience: “I suppose it’s most like being in the middle of a car wreck. “While it’s happening, you just feel oddly detached from it. It’s kind of, ‘I wonder how this will turn out. Am I going to die? Will I lose my life?’ as your car is spinning across the road into incoming traffic.”
