On his pot gut and sagging shoulders, Paul Giamatti carries this wry, baggy treatment of Mordecai Richler’s last novel. A Montreal TV hustler, drinker, hockey gambler, and womanizer, Barney is a Jewish rebel devoid of cause or much excuse. But Giamatti doses the story in his caustic charm, even as wife No. 1 (Minnie Driver) turns into a bulldozer and then loveable No. 2 (Rosamund Pike) wobbles away from him. There is some obscure plot filler, and Richard J. Lewis directed as if still filming episodes of CSI, but Giamatti fans can savor Barney and his touching, kvetching movie. (2011) — David Elliott
