Novel written by horror writer Stephen King. Published by Viking Press, the book was released in 1986.

It is the story of a group of childhood friends who return to their home town of Derry, Maine to fight an ancient evil that they battled years earlier. The evil which resides under the streets of Derry has been preying on the children of the town for years. Its main form is that of Pennywise the Clown, but the evil has the ability to take the form of that which you most fear.

The book is about King's warped nostalgic trip into those long summer afternoons that seemed to last forever and childhood friendships that we never believed would end. The group of friends that return are stereotypical of the outcast group of kids that existed in most neighborhoods:

Bill Denbrough, the all-American kid who talks funny (in this case a stutter)
Richie Tozier, the smart-mouth kid who hides his insecurity behind humor
Ben Hanscom, the fat kid
Mike Hanlon, the black kid
Stan Uris, the ethnic kid (in this case, Jewish)
Eddie Kaspbrak, the small and weak kid
Beverly Marsh, the girl

This rag-tag group fights an evil that threatens their very lives during a summer in the late 1950's. Once they drive the evil away, they promise to come back if it should ever return.

Like many of King's stories, It was adapted into a television mini-series. The mini-series, though respectable, did not possess the ability to draw the audience into the situation the way the book did. The cast included:

Richard Thomas as Bill Denbrough
Harry Anderson as Richie Tozier
John Ritter as Ben Hanscom
Tim Reid as Mike Hanlon
Richard Masur as Stan Uris
Dennis Christopher as Eddie Kaspbrak
Annette O'Toole as Beverly Marsh
Tim Curry as Pennywise the Clown

The mini-series also included a cast of younger actors playing the friends as children. Most of them were relative unknowns with two notable exceptions. Seth Green of Austin Powers and Buffy fame, played the young Richie Tozier and Jonathan Bradis of Seaquest DSV played the young Bill Denbrough.
