When It aired on ABC in November 1990, it arrived as a two-night miniseries adapted from Stephen King’s 1986 novel. No one expected it to become a generational touchstone, but it did. Ask almost anyone who grew up in the ’90s what scared them first and they’ll tell you about a grinning clown in the sewer, calling out from the dark.
The Basics
Directed by Tommy Lee Wallace, known for Halloween III: Season of the Witch and Fright Night Part 2, the miniseries ran about 192 minutes in total. Lawrence D. Cohen, who had already adapted King’s Carrie, handled the screenplay. The story follows two timelines. In 1960, a group of kids in Derry, Maine, call themselves the Losers’ Club and discover that their town is haunted by a shapeshifting creature that feeds on fear. Thirty years later, they reunite as adults after “It” returns.

Cast and Characters
The miniseries is remembered most for one thing: Tim Curry’s Pennywise. His performance mixes clown-show cheer with a streak of pure menace. It is the reason the production still has a hold on people today.
The child cast brings real heart to the story. Jonathan Brandis plays the stuttering but determined Bill Denbrough. Emily Perkins gives Beverly Marsh a mix of toughness and vulnerability. Seth Green’s Richie Tozier, Brandon Crane’s Ben Hanscom, Adam Faraizl’s Eddie Kaspbrak, Marlon Taylor’s Mike Hanlon, and Ben Heller’s Stanley Uris round out the group with a believable, lived-in chemistry.
As adults, the characters are played by Richard Thomas (Bill), Annette O’Toole (Beverly), John Ritter (Ben), Harry Anderson (Richie), Dennis Christopher (Eddie), Tim Reid (Mike), and Richard Masur (Stanley). The casting works because each adult feels like a future version of the kid we met earlier.

The Story in Short
Derry is a place where terrible things happen and people look away. Every 27 to 30 years, something ancient wakes up beneath the town and starts hunting children. The Losers’ Club fights It as kids, then promise to return if It ever comes back. Their “blood oath” is softened in the miniseries for network-TV standards (instead of a literal blood oath they share Eddie’s asthma inhaler), but the intent remains.
Three decades later, Mike Hanlon, the only Loser who stayed in Derry, calls the group home. A new wave of murders has begun. Pennywise is awake…and yes, sometimes cracking corny jokes when he’s not eating children.
How It Was Received
Critical reaction was mixed at first. Network horror was often dismissed, and some reviewers criticized the limited effects and toned-down violence. Part 2, in particular, earned complaints about dated visuals. But one thing everyone agreed on was Curry’s Pennywise. His work is still considered one of the great horror-villain performances.
Over time, the miniseries gained a more loyal following. Viewers praised the cast, the emotional weight of the story, and the focus on childhood friendship rather than gore. Today it sits firmly in cult-classic territory. Plus, at least in my opinion, the second half of the story isn’t as bad as some suggest…though yes, the first segment is still superior.
In fact, I will even argue the Chinese restaurant scene is far superior in the original miniseries than in the remake version.

The Legacy
The 1990 It left a deep mark on pop culture long before the 2017 and 2019 film adaptations revived the story for a new generation. For many people, it sparked a fear of clowns that never quite faded. Its structure — the split timeline, the return home, the unfinished business — helped shape modern genre storytelling. Stranger Things, with its focus on kids battling supernatural forces, owes it a clear debt. The show even cast Finn Wolfhard, who later played Richie in the 2017 film, completing the circle.
Differences from the Book
Network television in 1990 could only go so far, so the miniseries trimmed or removed entire subplots and softened much of King’s darker material. The cosmic side of the story, including the Turtle and the wider universe, is barely touched. The timeline was also shifted. In the novel, events take place in 1958 and 1985; the miniseries moves them to 1960 and 1990. And the final battle is simpler, more literal, and far less abstract than the version in the book.
Why It Still Matters
King once mentioned that he was 26 when he sold the rights to his first book (Carrie) for just $2,500. He later said he was simply lucky the deal happened at all. By this point in his career, King had already established himself, but Pennywise is definitely one of the characters we’ll forever remember Stephen King for.
Even with its limits, the miniseries continues to resonate. It delivers strong performances, especially from the child cast. It treats friendship and memory with sincerity. It carries the kind of small-town nostalgia King writes so well. Most of all, it introduced Pennywise to the world in a way no adaptation has topped for sheer presence and personality.
For many viewers, It (1990) remains the definitive screen version. For others, it was their first real scare, the moment they realized stories could follow them long after the screen went dark.
