It might seem unwarranted, or at least premature, to toss garlands at someone who's been on the job less than a year. But Keith Arnold had a laudable record on the Bay Area art house scene, notably as co-founder and programmer of the late, lamented Fine Arts Cinema in Berkeley, before he was hired at the end of last year to book and manage the precious Castro Theatre. It was an inspired choice, for the man has splendid taste, an unpredictable imagination, a gunslinger's guts, and a showman's soul — all the traits necessary for successful repertory programming in the post-DVD age. Arnold's bold moves have already included a run of Jean-Luc Godard's restored Weekend, the Children of Paradise restoration, big-screen salutes to Wong Kar-Wai, Terrence Malick, and Robert Altman, and a James Bond 50th anniversary blowout. Savor it: The city's movie palace is in terrific hands.
