Robert McCall, The Equalizer, was one of the great heroes of my teens. I also loved Edward Woodward in A Christmas Carol, The Wicker Man, and Hot Fuzz, guest spots in The Lone Gunmen and the Babylon 5 spinoff Crusade, and quite literally dozens of other roles. But I'll always remember him first and foremost as The Equalizer.
