Man of the House (1995)

Synopsis
A young boy attempts to sabotage his single mother's relationship with her new fiancé in this family-oriented comedy. Ben Archer (Jonathan Taylor Thomas) has become protective of his attractive mother Sandra (Farrah Fawcett) since they were abandoned by his father, and he resents the intrusion of anyone else into their lives. Despite his disapproval, however, Sandra has built up a relationship with district attorney Jack Sturges (an extremely low-key Chevy Chase), who eventually pops the question. Ben decides that marriage is out of the question, and he sets out to drive the lawyer away through a variety of schemes. These plans culminate in an effort to trick Struges into participating in the "Indian Guides," a scouting program involving all sorts of strenuous father-son activities. As one might expect, things do not quite go as Ben planned, as Jack proves himself a more suitable father figure than either expected. ~ Judd Blaise, All Movie Guide
