Mel Gibson isn’t Mel Gibson any more. The last time “that guy” appeared in a film was What Women Want. Since the Malibu DUI arrest he’s gotten too heavy and thin of hair to be an attractive box-office draw. To me he’ll always be the bearded wacko in the flannel shirt with a shave. The upside is that Edge of Darkness, an adaptation of a six-hour BBC miniseries, has been written by the great William Monaghan (The Departed) and the very competent Martin Campbell.
