“Up,” which begins in the nineteen-thirties, is steeped in the style of that period, with its gee-whiz appreciation of exotic adventure and its worship of heroes who have journeyed to strange, distant places. A little boy, Carl, watches newsreels at a theatre, and sees an explorer, Charles Muntz (Christopher Plummer), first celebrated then humiliated: no one believes the skeleton of a large flightless bird that Muntz has brought back from South America is authentic. When Carl leaves the theatre, he imagines the newsreel narrator describing his walk home, turning his stepping over a crack in the sidewalk into a vault over a canyon. It’s a gracious moment: the co-directors, Pete Docter and Bob Peterson, who also wrote the screenplay, pay affectionate tribute to daydreaming as a noble and necessary human activity. In dreams begin responsibilities, and in dreams begin movies, too.
