Like a child’s imagination on overdrive, this Robert Rodriguez lark careens through its espionage tale with wild abandon, following a brother and sister as they embark on a mission to rescue their kidnapped secret-agent parents (Antonio Banderas and Carla Gugino). Among the movie’s clever touches are pintsize submarines, quirky castles and bad guys called Thumb-Thumbs because they have giant fingers for arms and legs. This is the fun, goofy stuff of which kids’ dreams (and nightmares) are made.
