(out of 5) "The story of a former child star who runs a talent agency has built-in laugh spots. Especially with Michael J. Fox as the agent who needs a child star for a commercial or his agency will go under. Fox has a handle on comic reactions and gets to use them."--Video Movie Guide   Rated PG 106m DIR: James Lapine.
