Tim Curry. Honestly, we could probably stop the article right there and everyone would know exactly what we’re talking about. When people bring up the it original movie cast, they aren't usually thinking about the high-budget 2017 remake or the sequel with Bill Hader. They are thinking about a 1990 ABC miniseries that had no business being that terrifying. It was network television! You couldn't even show blood in certain ways back then, yet this group of actors scarred an entire generation of children who just wanted to watch a movie about friendship.
People forget how weird the casting was for this project. It was a massive gamble. You had a mix of seasoned character actors, a British theater legend playing a demonic clown, and a bunch of child stars who were actually, well, talented. Most horror movies from that era relied on jump scares. This cast relied on trauma.
The Clown in the Sewer: Tim Curry’s Shadow
It’s almost impossible to talk about the it original movie cast without centering the entire conversation on Tim Curry. He almost didn't take the role. He was hesitant because he had already spent so much time in heavy makeup for Legend as the Lord of Darkness, and he didn't want to go through that grueling process again. Thankfully for our collective nightmares, he said yes.
Curry’s Pennywise wasn't like Bill Skarsgård’s version. Skarsgård was otherworldly and twitchy. Curry? He was a mean Bronx butcher who happened to be a clown. He was loud. He was abrasive. He sounded like he’d yell at you for stepping on his lawn before eating your soul. That grounded, human-like quality made it so much worse because it felt like you could actually run into this guy behind a dumpster.
Interestingly, the rest of the cast actually stayed away from him on set. It wasn't because he was a "method" actor—Tim Curry is famously delightful—but because he looked so genuinely upsetting in that makeup that the child actors felt a natural, instinctual revulsion. That tension shows up on screen. When the kids look scared, they aren't always acting.
The Losers Club: A Bizarre Mix of TV Icons
The adult half of the it original movie cast is basically a "Who's Who" of 1980s and 90s television. Think about the lineup for a second. You had Richard Thomas, fresh off being John-Boy on The Waltons, playing the stuttering Bill Denbrough. You had John Ritter, the king of physical comedy from Three's Company, playing Ben Hanscom. It was a surreal collection of faces that audiences usually associated with comfort, not cosmic horror.
- Richard Thomas (Bill Denbrough): He had the hardest job. He had to lead the group while maintaining a believable stutter that didn't feel like a caricature.
- John Ritter (Ben Hanscom): Ritter brought a vulnerability to Ben that I don't think any other actor could have managed. You really felt the "sad kid" inside the successful architect.
- Annette O'Toole (Bev Marsh): She was the heart of the group. Her chemistry with the rest of the men felt lived-in and genuine.
- Harry Anderson (Richie Tozier): Most people knew him from Night Court. Playing a loud-mouthed comedian who is secretly terrified was right in his wheelhouse.
- Tim Reid (Mike Hanlon): Reid brought a gravitas to the role of the librarian/historian that kept the group grounded in the town's dark history.
The chemistry worked. It shouldn't have, but it did. Watching these TV veterans scream in a sewer while a guy in a yellow jumpsuit taunted them was peak 1990 entertainment.
The Kids Who Set the Standard
While the adults got the top billing, the younger members of the it original movie cast are often the ones fans remember most fondly. Jonathan Brandis, who played young Bill, became a massive teen idol shortly after this. His performance was soulful. It was heavy.
Then you had Seth Green as young Richie. Before he was in Austin Powers or Family Guy, he was this skinny kid with giant glasses cracking jokes to hide his fear. It’s one of the best "kid" performances in horror history because he captures that specific brand of middle-school bravado.
The dynamic between the kids felt like a real summer friendship. When they are hanging out at the Barrens or building the dam, you forget there’s a shape-shifting monster hunting them. You just want them to be okay. That’s the magic of the 1990 casting—they nailed the "club" aspect better than almost any other adaptation.
Why the 1990 Cast Still Holds Up
Look, the special effects in the original It haven't aged well. The giant spider at the end looks like it was made of papier-mâché and regret. It’s objectively silly. But the reason people still watch it is the it original movie cast.
They sold the terror.
When Pennywise appears in the photo album, the reaction from the kids isn't a "movie scream." It’s a frantic, panicked scramble. They make you believe that the stakes are real, even when the budget clearly wasn't. There’s a theatricality to the 1990 version that the modern movies lack. The new ones are "better" films technically, but the original has a soul that's hard to replicate.
Fact-Checking the Production Myths
You’ll often hear rumors that the cast was traumatized or that the set was cursed. That’s mostly internet nonsense. In reality, the set was quite collaborative. Director Tommy Lee Wallace has mentioned in various retrospectives that the biggest challenge wasn't the actors, but the sheer volume of the script. They had to condense a 1,100-page Stephen King novel into a four-hour television event.
The actors had to do a lot of the heavy lifting to fill in the gaps of the story that were cut for time. For instance, the deep lore about "The Turtle" and the macroverse was completely stripped out. The cast had to convey that cosmic dread through their performances alone. They didn't have CGI to show the "Deadlights." They just had to look into a light and act like their minds were breaking.
Actionable Insights for Horror Fans
If you're looking to revisit the work of the it original movie cast, don't just stop at the miniseries. To truly appreciate the range of these actors, you have to look at their surrounding work from that era.
- Watch Tim Curry in Legend (1985): To see how he handles heavy prosthetics compared to the relatively "simple" Pennywise makeup.
- Check out John Ritter in Sling Blade: This shows his incredible dramatic range outside of the "funny man" persona he brought to It.
- Find the "It" Commentary Tracks: If you can get your hands on the DVD/Blu-ray, the commentary with the director and some cast members is a goldmine for understanding how they pulled off certain scares on a TV budget.
- Compare the Stuttering: Watch Richard Thomas’s performance side-by-side with Jaeden Martell’s in the 2017 version. It’s a masterclass in how different actors interpret the same character trait.
The 1990 miniseries is a relic of a different time in television history. It was an era when "Event TV" meant the whole world stopped to watch. The it original movie cast was a huge part of that cultural moment. They proved that you didn't need a R-rating or $100 million to create something that would stick with people for thirty years. They just needed a good script, a creepy sewer set, and Tim Curry in a wig.
To get the full experience today, watch the first half (the "kids" era) in a dark room with no distractions. Ignore the dated stop-motion. Focus on the eyes of the actors when they see the red balloon. That’s where the real horror lives. The legacy of this cast isn't just that they made a hit show; it's that they defined what Stephen King's world felt like for an entire generation.
