When Chris Pratt first started dating Katherine Schwarzenegger, the internet didn't just look at the couple. They looked at the father. Everyone wanted to know how the guy who played Star-Lord would handle the guy who played the Terminator. But while the memes were busy imagining Arnold Schwarzenegger chasing Pratt around with a shotgun, a much more interesting, grounded relationship was actually forming behind the scenes. It wasn't just about the father-in-law; it was about the brother-in-law.
Chris Pratt and Patrick Schwarzenegger have developed one of the most visible and genuine "bromances" in Hollywood, and it’s not just for the cameras. Honestly, if you look at their history, it’s a masterclass in how to merge two high-octane celebrity lives without the usual ego trips.
Why the Chris Pratt and Patrick Schwarzenegger Bond Actually Works
It started back in 2018. Before there was a wedding or kids, there were basketball games. Pratt was spotted courtside with Patrick at an LA Clippers game long before the engagement was even official. People assumed it was just a "get to know the family" move, but they’ve stayed tight ever since.
Basically, they share a very specific vibe. Both guys are fitness junkies. Both are deeply embedded in the "action hero" genre. And both have a weirdly similar sense of humor—that self-deprecating, slightly goofy energy that makes them feel more like normal guys than A-list stars.
The Gym Test
We have to talk about the gym because, in that family, the gym is the church. Arnold famously told Jimmy Kimmel that Pratt won him over during an incline press session. But it was Patrick who really helped bridge the gap between Pratt’s "Parks and Rec" past and his "Jurassic World" future. They work out together. Not just "celeb trainer" workouts, but grueling sessions that would break most people.
Working Together on The Terminal List
Most in-laws barely want to share a Thanksgiving table, let alone a film set. But when Pratt was casting for the Amazon Prime series The Terminal List, he didn't just give Patrick a courtesy call. He put him to work.
Patrick played Donny Mitchell, the youngest member of the SEAL team. Pratt, who executive produced the show, was reportedly "beyond proud" of Patrick’s performance. But it wasn't a handout. Patrick had to go through the same tactical training as everyone else. Pratt even joked that he enjoyed seeing his brother-in-law get "tortured" during the grueling boot camp scenes.

"He’s such a hardworking guy," Patrick told People magazine. "I think the best thing I learned from Chris was attitude. That guy comes onto set every day and just creates a positive culture."
Mentorship or Rivalry?
There’s a ten-year age gap between them. Pratt is the seasoned vet; Patrick is the rising star carving out a niche in projects like The White Lotus and Gen V. In Hollywood, that's usually a recipe for competition. Instead, Pratt has become something of a hype-man for Patrick. When the third season of The White Lotus premiered in 2025, Pratt was all over social media calling it the "decade of Patrick Schwarzenegger."
The Marriage Connection
Let’s be real: none of this happens without Katherine. She’s the glue. When Chris and Katherine married in June 2019, the Schwarzenegger-Shriver clan could have been intimidating. You've got Kennedy royalty on one side and a bodybuilding icon on the other.
Patrick, however, was one of the first to publicly embrace Pratt. He’s been a constant fixture in their lives, from helping Pratt plan a surprise proposal to being a "fun uncle" to Lyla, Eloise, and Ford. He even admitted on The Kelly Clarkson Show that he leaned on Chris for advice when he was getting ready to propose to his now-fiancée, Abby Champion.
What Most People Get Wrong About Them
The biggest misconception? That it’s all about the "Schwarzenegger" brand.
People think every move they make is a calculated PR play to keep the family in the headlines. If you watch them at a premiere, though, it’s different. At the White Lotus Season 3 premiere in February 2025, the whole family showed up. Pratt wasn't there to steal the spotlight; he was there in jeans and a jacket, standing in the back, letting Patrick have his moment.
It’s a rare thing in Hollywood: a relationship that survived the "in-law" phase and turned into a legitimate friendship.
How to Build a Real Connection (The Pratt-Schwarzenegger Way)
If you're looking for a takeaway from how these two navigate their high-profile lives, it's actually pretty simple.
- Shared Interests Matter: Find the "gym" in your own life. For them, it was fitness. For you, it might be gaming or DIY projects. Having a physical activity to do together removes the pressure of forced conversation.
- Support, Don't Compete: Pratt is a Marvel lead, and Patrick is a TV star. They aren't trying to play the same roles. Acknowledge each other's wins without making it about yourself.
- Show Up for the Small Stuff: It’s not just about the red carpets. It’s about the Thanksgiving football games and the random basketball outings that happen when the cameras aren't supposed to be there.
The reality of the Chris Pratt and Patrick Schwarzenegger dynamic is that they’ve stopped being "the guy who married my sister" and "my wife's brother." They've become peers. In an industry built on temporary alliances, that’s actually pretty impressive.
Keep an eye on their upcoming projects. With Pratt continuing his run in The Terminal List universe and Patrick’s star rising in the HBO landscape, it’s only a matter of time before we see them share the screen again. But even if they don't, you can bet they'll be at the same gym at 6:00 AM tomorrow.
