Adulthood (2025): A Dead Body, Sibling Chaos & The Unexpected Journey Into Crime

Josh Gad and Kaya Scodelario Star in This Twisted Dark Comedy Thriller

“Adulthood: where the skeletons in your closet are actually buried in the basement.”

When you think about growing up, you expect awkward job interviews, tax confusion, and maybe a panic attack at IKEA. But in Alex Winter’s new dark comedy-drama, Adulthood, adulthood comes with a body count. Literally.

Set to premiere at the 2025 Toronto International Film Festival and heading to select theaters on September 19 (with a digital release on September 23), this wickedly sharp, genre-blending film is about what happens when two siblings stumble across a corpse and begin unraveling a family secret that spirals into lies, betrayal, and murder.

🧱 The Premise: Siblings, Secrets & Suburban Sin

Megan (Kaya Scodelario) and Noah (Josh Gad) are your typical adult siblings: a little dysfunctional, a little snarky, and barely holding their lives together. That is, until they return home for a visit and find a long-dead body buried in their parents' basement. Who is it? How did it get there? And what are they supposed to do about it?

What starts off as a shock turns into a twisted rabbit hole of crime, cover-ups, and increasingly bad decisions. As their paranoia deepens and the body count rises, Megan and Noah are forced to confront not only the sins of their family, but the terrifying possibility that they might be just as capable of darkness.

“It’s like Knives Out meets Arrested Development — with a shovel and a nervous breakdown.”

🎭 Meet the Cast: Murder Has Never Been So Star-Studded

• Kaya Scodelario as Megan – Sharp, sarcastic, and increasingly unhinged.

• Josh Gad as Noah – Lovable, anxious, and one wrong step away from a full meltdown.

• Billie Lourd, Anthony Carrigan, and Alex Winter add to the escalating chaos with deliciously quirky performances that toe the line between sinister and slapstick.

Directed by Alex Winter (The Lost Boys, Zappa) and written by Michael M.B. Galvin, the film balances absurd comedy with real emotional tension, wrapped inside a mystery that peels back layer after layer of generational guilt and domestic dysfunction.

🎬 A Satirical Look at “Being a Grown-Up”

While the body in the basement is the literal skeleton, Adulthood cleverly explores metaphorical ones too: the lies we inherit, the secrets we protect, and the moments that force us to grow up — whether we’re ready or not.

Amid the chaos, there's poignant commentary on:

• 👨‍👩‍👧‍👦 Dysfunctional family dynamics

• 🧠 Mental health, anxiety, and sibling trauma

• 💼 What it really means to be an adult in a world built on lies

Think of it as a comedic gut-punch wrapped in suspense — part Fargo, part Little Miss Sunshine, with a dash of Coen Brothers energy.

🔍 Final Thoughts: Digging Deep — Literally & Emotionally

In Adulthood, the phrase "digging up the past" is no longer a metaphor. It’s messy, it’s weird, it’s darkly hilarious — and it might just be the most unexpected indie gem of the year. Whether you're in it for the mystery, the comedy, or the existential crisis, this film promises one wild descent into suburban secrets.

“Some families bury their secrets. This one forgot where they left the shovel.”

So, bring your siblings (or don’t), and get ready for a smart, sharp ride into the darker side of growing up — coming soon to a theater (or your basement) near you. 🧹🪦💀
