Who should a kid"s hero be? In this underrated adventure-comedy, that"s the central issue. Henry Thomas, fresh from E.T., plays a San Antonio kid whose father (Dabney Coleman) doesn"t spend nearly enough time with him. So the boy loses himself in video games--and even has an imaginary friend (also played by Coleman), a super-resourceful secret agent. When he accidentally comes into possession of a spy group"s secret plans, and winds up on the run from them, he must learn to rely on himself (and his imaginary pal) to save his skin. But, in the end, Dad proves to be his real hero in this engaging and solid family film. --Marshall Fine
