Hollywood is full of families that try too hard. You see them on red carpets, awkwardly posing while trying to convince us they’re just like any other siblings. But then you have the Cusacks.
Honestly, Joan Cusack and John Cusack are the gold standard for what happens when talent and genuine family chemistry collide. They don't just "tolerate" each other for the sake of a paycheck. They’ve shared the screen in ten different movies over four decades. From the neon-soaked 80s to the gritty indie era of the early 2000s, their collaboration is basically a timeline of modern American cinema.
They’re weird. They’re relatable. And they’re never boring.
The Chicago Roots of an Acting Powerhouse
It all started in Evanston, Illinois. The Cusack house wasn’t your typical suburban home. Their father, Dick Cusack, was a filmmaker and actor himself. He didn't just tell them to go play outside; he nurtured a specific kind of creative chaos.
Think about it.
You’ve got John, Joan, and their other siblings—Ann, Bill, and Susie—all ending up in the industry. It wasn’t a "stage parent" situation. It was more of a "this is what we do" family vibe. Joan, being the older sister, paved the way. She’s got this incredible, elastic face and a voice that can go from a whisper to a frantic squeak in a second. John? He became the quintessential everyman with a darker, more cerebral edge.
Every Movie Where They Shared the Screen
If you’re trying to track the Joan Cusack and John Cusack filmography, you’re looking at ten specific films. Some are iconic. Others are deep cuts that only true cinephiles talk about at 2:00 AM.

- Class (1983): Their first time together. It’s a messy teen comedy, but it set the stage.
- Sixteen Candles (1984): John is the "Geek" sidekick to Anthony Michael Hall. Joan is the "Geek Girl" with the neck brace. It's tiny, but it's there.
- Grandview, U.S.A. (1984): They actually played brother and sister here. Typecasting? Maybe. Effective? Absolutely.
- Broadcast News (1987): A masterpiece. Joan is the frantic assistant; John has a blink-and-you'll-miss-it cameo as an angry messenger.
- Say Anything... (1989): This is the one. John is Lloyd Dobler, the boombox-holding icon. Joan plays his sister, Constance. Their scenes together feel so lived-in because, well, they were.
- Grosse Pointe Blank (1997): This is arguably their best collaboration. John is a hitman; Joan is his high-strung assistant, Marcella. The way they bicker over "deteriorating" targets is comedy gold.
- Cradle Will Rock (1999): An ensemble piece directed by Tim Robbins.
- High Fidelity (2000): John is the record store owner going through a mid-life crisis. Joan is the friend who finally tells him he’s being an idiot.
- Martian Child (2007): A softer, more emotional turn where they play siblings again.
- War, Inc. (2008): A spiritual successor to Grosse Pointe Blank. It’s weird, political, and very "Cusack."
The "Grosse Pointe Blank" Magic
Let’s talk about 1997.
Grosse Pointe Blank is the peak of their professional relationship. John co-wrote the script, so he knew exactly how to use Joan’s strengths. She isn’t just a sidekick in this movie. She’s the anchor. While John’s character, Martin Blank, is literally killing people, Joan’s Marcella is on the phone screaming about office supplies and "boring soup."
It’s hilarious. It’s also kinda sweet.
There’s a shorthand between them that you can’t fake. You can see it in the way they talk over each other. Most actors have to rehearse for weeks to get that level of timing. For them, it’s probably just how they talked over the dinner table in Evanston.
Why Joan is the Secret Weapon
People often focus on John because he was the leading man for so long. But let's be real: Joan Cusack is a powerhouse. She has two Academy Award nominations (Working Girl and In & Out). She won an Emmy for Shameless.
She has this "unhinged best friend" energy that is impossible to replicate.

Whenever she shows up in a John Cusack movie, the energy shifts. She makes him better. She grounds his "moody intellectual" routine with a dose of Midwestern reality. Honestly, a lot of John’s best movies feel a little bit emptier when she isn’t in the credits.
The Rumors and the "Almost" Castings
Did you know they were almost cast as a married couple?
Yeah. It almost happened in the remake of Fun with Dick and Jane. They both eventually walked away from it because—rightfully so—they thought it would be too weird to play husband and wife.
"It’s just not right," they basically said.
That’s the thing about the Cusacks. They have boundaries. They know that their brand is built on that sibling dynamic, and trying to subvert it for a paycheck would just feel... icky.
What Are They Doing Now in 2026?
John has shifted a lot of his energy toward activism and independent projects lately. He's always been a bit of a rebel in Hollywood, preferring to do things his own way. In June 2026, he's actually releasing a graphic novel called Momo. It’s a surrealist, cosmic road trip story. It sounds exactly like something he’d do—unconventional and slightly dark.

Joan is still the queen of the character actors. She’s set to return as the voice of Jessie in Toy Story 5, which is currently in production. She also pops up in prestige TV every now and then, usually stealing every scene she’s in.
They don't work together as much as they used to, which is a bummer for us. But their legacy is already cemented.
