Frustrated at being too small for the girl he likes, thirteen-year-old Josh makes a wish at a grimy carnival fortune-telling machine and wakes the next morning trapped in the body of a grown man. Fleeing home before his baffled mother can call the police, he lands a job testing toys at a Manhattan company, where his genuine childlike instincts rocket him up the corporate ladder and into a grown woman's affections. Penny Marshall's beloved comedy lets Tom Hanks play delighted innocence to perfection, from the giant floor piano to the ache of a boyhood slipping away. A warm, wistful fantasy about the bittersweet cost of growing up too fast.
