When is a movie fall-down funny even when some scenes fall flat on their fat ones? When its Anchorman 2: The Legend Continues. Thats because from the moment Will Ferrell steps into the blazer of Ron Burgundy, the San Diego news anchor whose ego masks gargantuan stupidity and insecurity, Im a lost cause to laughter. Its been nearly a decade since Ferrell played the role, but it still fits him like a comedy glove. Or maybe its just that the sequel is really the same movie with a slight update. Im not bitching. Really. Director and co-writer Adam McKay, possessed of a mad gene to equal Ferrells, has updated the plot from the 1970s to 1980 when Ron, fired in San Diego and replaced as head anchor by his now ex-wife (Christina Applegate), has moved to Manhattan to head a 24-hour news channel that even he doesnt believe in. With him are weatherman Brick Tamland (Steve Carell), sports guy Champ Kind (David Koechner) and studly reporter Brian Fantana (Paul Rudd). Im not going to spoil the jokes by telling you what these idiots do (its mostly more idiot stuff). But I will tell you I can watch them do it forever.
