Chris Pratt’s big-little-brother moment in Mercy turned into a full-moon special when Cully Pratt’s stunt pants surrendered mid-shoot, exposing everything from crack to curls in front of the entire crew and a closing elevator door.
Chris Pratt arrived on Jimmy Kimmel Live! January 16 with a story so visceral it instantly eclipsed any traditional late-night plug: his older brother Cully Pratt literally exploded out of his costume while filming a death scene for the upcoming sci-fi thriller Mercy.
The sequence required Cully—an ex-Marine turned occasional actor—to play a security guard gunned down in a futuristic courthouse policed by an AI judge. Squibs (mini explosive charges rigged to burst fake blood) were taped to the inside of his uniform pants. Between takes, production swapped him into replacement trousers two sizes too small. Chris recalled warning him, “It’s fine, it’s fine,” only to watch the inseam surrender from “the top of his ass crack to above his pubes” the instant Cully hit the floor.
The coup de grâce came from a practical-effects elevator door timed to close on Cully’s “dead” body. “As he goes down, the doors pinch him and he yells, ‘Uh, my d***’s out,’” Chris laughed, noting the entire crew saw the full monty before someone finally yelled cut.
Why the Moment Matters Beyond the Meme
- Authentic sibling chemistry on set: Director Timur Bekmambetov kept the take, using the genuine shock on nearby actors’ faces to heighten the scene’s tension.
- Pratt family brand reinforcement: Chris has built a persona around affable, self-deprecating storytelling; letting Cully own the punchline extends that relatability without oversharing about his own private life.
- Indie sci-fi buzz boost: Mercy—about a detective (Chris Pratt) fighting a 90-minute AI trial to prove he didn’t murder his wife—needs viral chatter to cut through the January box-office lull. A pants-splitting anecdote delivered exactly that.
From Stunt Mishap to Marketing Gold
Studios rarely confirm whether embarrassing outtakes make final cut, but Bekmambetov’s past projects (Wanted, Hardcore Henry) revel in kinetic, unpredictable energy. Keeping a flash of Cully’s catastrophe—even for a single frame—signals to genre fans that Mercy won’t sanitize its suspense for PG-13 comfort.
Meanwhile, Chris’s chair-strapping request for his own courtroom sequences—revealed at New York Comic Con—shows the star’s appetite for immersive tension. “I asked them to confine me,” he told the panel. “You naturally feel claustrophobia, and that was helpful.” If the lead actor insists on real restraints, letting his brother actually lose his pants fits the same authenticity playbook.
What’s Next for the Pratts
Mercy lands in theaters January 23, giving audiences their first chance to spot (or miss) the infamous wardrobe malfunction. Off-screen, Cully—already a fan favorite on Chris’s Instagram—could parlay the moment into more stunt-casting offers, capitalizing on a willingness to suffer for the shot. Chris, fresh off The Electric State and gearing up for another Guardians of the Galaxy press cycle, continues to leverage late-night platforms for narrative control, turning potential PR disasters into endearing family lore.
