It

It (also known as Stephen King's IT) is a 1990 ABC two-part psychological horror drama miniseries directed by Tommy Lee Wallace and adapted by Lawrence D. Cohen from Stephen King's 1986 novel of the same name. The story revolves around a predatory monster that can transform itself into its prey's worst fears to devour them, allowing it to exploit the phobias of its victims. It mostly takes the humanoid form of Pennywise, an evil clown. The protagonists are The Lucky Seven, or The Losers Club, a group of outcast kids who discover Pennywise and vow to kill him by any means necessary. The series takes place over two different time periods, the first when the Losers first confront Pennywise as children in 1960, and the second when they return as adults in 1990 to defeat him a second time after he resurfaces.

Cast members included Tim Curry (Pennywise), Richard Thomas, Annette O'Toole, John Ritter, Harry Anderson, Jonathan Brandis, Tim Reid, Dennis Christopher, and others. Produced by Green/Epstein Productions, It was filmed over a period of three months in Vancouver, British Columbia, in mid-1990 with a budget of $12 million, double the usual television budget. The miniseries was first broadcast during the November sweeps month. Despite the risk factors, mixed pre-airing critical reviews, and coverage of President George H. W. Bush's foreign trips cutting into the program, It was ABC's biggest success of 1990; the miniseries pulled through with a total of 30 million viewers for its two parts.
