A decade ago, Tomm Moore startled the world by landing an Oscar nomination for “The Secret of Kells,” an independent animated feature that wowed those who saw it with its distinctive look (extrapolated from illuminated manuscripts) and near-phosphorescent palette (leaves so green they practically glow in the dark). At the time, outsider animation hardly stood a chance against Hollywood studios, but now, no one should be surprised if he lands another for “Wolfwalkers,” whose dazzling visual design makes “Kells” look positively prehistoric by comparison.
