In its third season, Home Improvement settled into a comfortable and hugely popular groove. Tim Taylor (Tim Allen, The Santa Clause, the voice of Buzz Lightyear in Toy Story) banters fondly with his wife Jill (Patricia Richardson, Ulee's Gold) at home, snipes at his assistant Al (Richard Karn, Sex and the Teenage Mind) on his TV show Tool Time, and discusses manly troubles with his philosophical neighbor Wilson (Earl Hindman), while his three sons (Taran Noah Smith, Zachary Ty Bryan, and Jonathan Taylor Thomas, who was the voice of the young Simba in The Lion King) run amok. The season introduces a few new faces: Debbe Dunning replaces Pamela Anderson as the Tool Time girl; Al gets a girlfriend, Ilene (Sherry Hursey); several episodes features some new neighbors (Mariangela Pino and Robert Picardo, later the Doctor on Star Trek: Voyager); the great M. Emmet Walsh (Blood Simple) appears as Jill's father; and a number of sports figures, shuttle astronauts, and former President Jimmy Carter make guest appearances as themselves.
