Wes Anderson (“The Royal Tenenbaums”) transports his arch, pristine, melancholic sensibility to India, where three estranged brothers meet after their father’s death and hop a train in a quixotic attempt to heal their spiritual wounds. The oldest is the bossy, gung-ho Francis (Owen Wilson), his face swathed in bandages after a motorcycle crash. The suave and shifty middle brother, Peter (Adrien Brody), is terrified of fatherhood. The well-dressed but barefoot writer Jack (Jason Schwartzman) is obsessed with his ex-girlfriend. A return to form after the flat “Life Aquatic,” “Darjeeling” has a lightweight, coloring-book charm that deepens and darkens after these odd, privileged ducks are thrown off the train. They seek out their elusive mother (Anjelica Huston), who has become a nun in the Himalayas. You immediately see where Francis got his bossiness— and her sons got their prodigious noses.
