Pixar is still tops when it comes to animation, but don’t overlook Dreamworks’How to Train Your Dragon,recently out on DVD. The movie’sunlikely herois Hiccup Horrendous Haddock III, a scrawny Viking who uses brains over brawn to befriend a wounded dragon. The real star, however, is legendary cinematographer Roger Deakins, who directed the 3-D flight sequences. The whoosh-bang joy of fire-breathing dragons soaring through the sky is a reminder of why we still go to the movies.
