It premieres on ABC in 1990. The first adaptation of Stephen King’s novel is a two-night miniseries and stars Harry Anderson, John Ritter, Annette O’Toole and Tim Curry. The boundary-pushing program is a hit and over time, develops a cult following despite the limitations of TV at the time and only measured approval from King.
