13-year-old Josh makes a wish at a carnival fortune-teller to be big. When he wakes up the next morning he finds that he suddenly won't fit into his clothes and his mother doesn't recognize him. Until he finds a cure, he must learn to live in the adult world--complete with job (in a toy firm), Manhattan apartment, and romance. Perkins is wonderful as a cynical fellow employee who warms to the new guy's naivete, while Hanks is totally believable as the little boy inside a man's body. Marshall directs with authority and the whole thing clicks from the beginning.
