Loosely based on Chris Van Allsburg's sequel to Jumanji. Our heroes are rival brothers Danny (Jonah Bobo) and Walter (Josh Hutcherson). Walter, who's approaching adolescence and determined to act older, is fiercely competitive and good at sports. Danny still loves toys and board games, and has a vivid imagination, but in order to keep up with his brother, he has also learned how to cheat to win. When Danny discovers a shiny retro-antique board game made of tin, with a clockwork mechanism that moves the pieces and dispenses cards, Walter wants no part of it. But once Danny starts it up, outer space comes vividly to life in the form of a meteor shower, followed by the discovery that the house itself is now floating in space, in orbit around a Saturn-like planet. Neither pandering nor dull, Zathura plays exactly like a no-limits replica of the kind of space adventure that imaginative kids left to their own devices might enact.
