It’s not easy to make tedious office work funny, but Haiku Tunnel does just that. Kornbluth (who directed with his brother Jacob) plays a temp assigned to the San Francisco law firm S&M. Things go so well the first day that his supervisor (Shumaker) offers him a full-time gig. ”You go perm and the firm will cover your…psychotherapy,” she says enticingly. Kornbluth — a nudgier, pudgier Woody Allen — is a hoot, though the scenes in which he speaks directly to the camera fall disappointingly flat. Still, anyone who’s ever temped or thought a lawyer was the devil will appreciate Haiku Tunnel’s mordant look at corporate life.
