Someone asked about black and white vs. color movies recently, and one could make a case for each. But Don Knotts, who died yesterday, was the perfect character inside that TV set in the mostly black and white film Pleasantville. Of course, he's best known as Barney Fife on Andy Griffith Show, a five-time Emmy winner. The show suffered greatly after his departure. I watched religiously for the well-meaning, but inept deputy to mangle something that Sheriff Taylor would put aright. But Barney always had a good heart, right under the pocket where he usually kept that one bullet for his gun. I even watched an episode of Matlock, just to see Andy and Don back at work. He almost was enough to make me watch Three's Company, but not quite. *** Johnny B. notes the death of "Kolchak: the Night Stalker" star Darren McGavin.
