Golden Years is a 1991
Stephen King miniseries starring
Frances Sternhagen and
Keith Szarabajka. Szarabajka plays Harlan Williams, a
janitor for a research facility who is exposed to some really funky stuff in a lab explosion, and begins to grow younger instead of older. The
U.S. government, in part to cover up their experiment, and in part to figure out how Williams is growing younger, begins a country-wide manhunt for the lucky fellow.
The Bowie song of the same name served as the theme song for the four hour miniseries.
