The puppets are only part of the breathtaking effects in “Life of Pi.” We’re plunged into a world that’s at times hellish, at times heavenly, by a masterful team of designers – Tim Lutkin’s lighting, Carolyn Downing’s sound, Andrzej Goulding’s video and animation, Tim Hatley’s sets and costumes — Andrew T Mackay’s music, and, crucially, by the two dozen cast members, who are fully integrated into not just the action but also the scenery.
