Look, we’ve all been there. You’re scrolling through a streaming app at 11:30 PM, your brain is fried, and you just want something that feels like a warm, slightly inappropriate hug. You want that specific 2007 energy. You want movies similar to knocked up.
The thing about Seth Rogen and Katherine Heigl’s accidental-pregnancy masterpiece isn’t just the bong rips or the "mushrooms in Vegas" sequence. It’s that weird, uncomfortable, yet totally relatable transition from being a total loser to realizing you might actually have to keep a tiny human alive. It’s "slacktire" comedy at its peak.
Finding that same vibe in 2026 is actually harder than it looks. Most modern comedies feel like they were written by a board of directors trying to be "viral." But some gems—both old and surprisingly recent—hit that sweet spot of being absolutely filthy while also making you kind of want to call your mom.
The Apatow Universe: More Than Just Dick Jokes
If you’re hunting for movies similar to knocked up, you basically have to start with the source. Judd Apatow didn’t just direct a movie; he created a whole ecosystem of bearded men who refuse to wear pants.
The 40-Year-Old Virgin (2005)
This is the big bang of the genre. Honestly, if you haven’t seen Steve Carell get his chest hair ripped out while screaming "Kelly Clarkson!", what are you even doing with your life? It’s got that exact same DNA as Knocked Up. You’ve got the ensemble cast—Paul Rudd, Seth Rogen, Jonah Hill in a tiny cameo—acting like real friends who just roast each other because they don't know how to talk about feelings.
It’s about a guy who is "stunted," much like Ben Stone. Ben is stunted by weed and a lack of ambition; Andy is stunted by a literal lack of sexual experience. Both movies follow the same emotional arc: a man-child forced to interact with the real world because of a woman who is, frankly, way out of his league.

This Is 40 (2012)
Think of this as the "spiritual sequel" that actually features the same characters. It follows Pete (Paul Rudd) and Debbie (Leslie Mann) from Knocked Up as they hit middle age. If Knocked Up was about the terror of starting a family, this is about the exhaustion of maintaining one. It’s got a lot of screaming. Like, a lot of screaming. But it feels real. It captures that specific marital anxiety where you love someone but also kind of want to push them out of a moving car because they didn't buy the right kind of milk.
When the Pregnancy Isn’t the Only Disaster
Sometimes you don’t need the baby plot. You just need the "immature person forced to grow up" plot. These are the movies that keep that R-rated heart beating.
Forgetting Sarah Marshall (2008)
Jason Segel wrote this based on his own breakups, and you can tell. It’s raw. It’s embarrassing. There’s full frontal male nudity in the first five minutes just to establish how vulnerable (and pathetic) Peter is.
Why is it like Knocked Up? Because it’s a comedy that respects its characters. Even the "villains" like Sarah Marshall or her new boyfriend Aldous Snow (played by a peak-chaos Russell Brand) aren't one-dimensional. They’re just people trying to figure out how to be happy while making a mess of everything. Plus, Bill Hader is there to provide the "rational friend" commentary that every Apatow-adjacent movie needs.
Trainwreck (2015)
Amy Schumer and Bill Hader flip the script here. Instead of the guy being the mess, it’s Amy. She’s the one who’s terrified of commitment, drinks too much, and treats relationships like a chore. Directed by Apatow, it has that "meandering" feel where scenes breathe and the jokes feel improvised. The chemistry between Schumer and Hader is surprisingly sweet, much like Ben and Alison.

- Key Insight: These movies work because they aren't afraid of the "boring" parts of life. They find the humor in the hospital waiting rooms and the awkward dinners.
The New Wave: 2020s Comedies With Old Souls
The "raunchy comedy" supposedly died in the 2010s, but that’s a lie. It just evolved. If you want movies similar to knocked up but want something that doesn't feel like a time capsule from the Bush era, look here.
The King of Staten Island (2020)
Pete Davidson basically plays a version of himself, which is to say, a guy who is deeply stuck. It’s longer than it needs to be—a classic Apatow trait—but it’s incredibly soulful. It deals with grief, firemen, and the struggle to do literally anything productive with your day. It’s the closest thing we’ve had to the Knocked Up "growing pains" vibe in years. Marisa Tomei is phenomenal as the mom who is just done with her son’s nonsense.
No Hard Feelings (2023)
Jennifer Lawrence proved she has the comedic chops to carry a raunchy, old-school R-rated comedy. The premise is ridiculous: wealthy parents hire a woman to "date" their socially awkward son before he goes to college. But underneath the "fight on the beach while naked" scene (which is hilarious, by the way), there’s a real story about two people who are lonely in very different ways. It’s got that same "unlikely duo" energy that made Ben and Alison work.
Bottoms (2023)
Okay, hear me out. This is basically Superbad but for the girls and the gays. It’s absurd, it’s violent, and it’s deeply weird. But the core of the movie is about high school losers trying to gain some semblance of status. It captures that "group of friends against the world" feeling that the Knocked Up crew (Jason Segel, Jay Baruchel, Martin Starr) did so well.
Why These Movies Still Hit Hard
People often get it wrong. They think these movies are popular because of the weed jokes or the swearing. That’s just the surface.

The real reason we keep looking for movies similar to knocked up is because of the honesty. Most rom-coms are fake. They feature people with perfect apartments and perfect jobs who have "cute" problems. Knocked Up featured a guy who lived in a house that smelled like old bong water and a girl who was legitimately terrified that her life was over because she had a one-night stand with a loser.
It’s about the "slacktire" aesthetic. It’s about being "dorky and deep." When Ben Stone tries to read the pregnancy books but gets distracted or when he tries to be the "man of the house" but fails miserably, we see ourselves.
The Misconception About "Man-Children"
A lot of critics at the time (including Katherine Heigl herself in a famous Vanity Fair interview) thought the movie was sexist or celebrated immature men. But if you watch it closely, the movie is actually pretty hard on Ben. It doesn't say "stay a loser." It says "hey, being a loser is comfortable, but eventually you have to show up for the people you love." That’s a universal message that transcends the 2007 frat-pack vibe.
Actionable Tips for Your Next Movie Night
If you’re planning a marathon, don’t just pick at random. You have to curate the vibe.
- Check the "Apatow Mafia" Credits: Look for names like Seth Rogen, Evan Goldberg, Paul Rudd, or Jason Segel. If two or more are involved, you’re usually in the right ballpark.
- Look for the "R" Rating: These movies need the freedom to be vulgar. Without the "crassness," the "heart" usually feels unearned and cheesy.
- Prioritize Improvisation: The best scenes in these films feel like people just talking. Movies like Step Brothers or Pineapple Express thrive on this.
- Balance the Raunch with Reality: If a movie is just jokes and no stakes, it’ll feel empty. You want a movie where the characters actually have something to lose.
Basically, the best movies similar to knocked up are the ones that make you laugh until your stomach hurts and then quietly remind you that being an adult is just one long series of "failing upwards" until you finally get it right.
To get the most out of this genre, start with The 40-Year-Old Virgin to see the blueprint, then move to Forgetting Sarah Marshall for the emotional payoff, and finish with The King of Staten Island to see how the "stunted man" trope has aged into the modern day. It’s a journey through the messy, loud, and weirdly beautiful reality of growing up when you really, really don't want to.
