From the outside, acting looks easy: memorize a script, hit your mark, collect a hefty paycheck and wait for applause. But peel back the red carpets and champagne toasts, and you’ll find moments that make stars squirm years later. Sometimes it’s a mistimed gag that still haunts reruns, sometimes it’s nudity they never wanted, sometimes it’s a storyline that felt a little too close to real life.
Here are 15 times the cameras rolled and actors thought, “Yeah… this should’ve stayed on the cutting room floor.”
John Cleese – Fawlty Towers
Fawlty Towers is now considered to be a comedy classic, but actor John Cleese still can’t laugh at one particular scene with an infamous moose head. It was supposed to drop on cue. It didn’t. He stands there, visibly waiting for it like a man spotting rain clouds, and the whole thing aired anyway. His regret? That nobody just yelled “cut” and tried again. Now it’s immortalized in syndication.
Naya Rivera – Glee
Santana’s savage one-liners were iconic. But in the episode Jagged Little Tapestry, her rant at Kurt landed too hard. Rivera admitted it felt so personal that it upset Chris Colfer in real life. Having to spit those lines over and over blurred the line between performance and cruelty. For Rivera, it was less comedy, more cringe.
Gordon Ramsay – Hotel Hell
Yes, the same guy who screams “idiot sandwich” for a living. On Hotel Hell, Ramsay agreed to test a shower… fully nude. His bare backside made it to air, and he instantly regretted the whole thing. Quote: “I do regret one thing — getting my [expletive] out in the shower.” Translation: not every recipe needs spice.
Penn Badgley – You
Playing Joe Goldberg is already a one-way ticket to Creepsville, but one scene still disgusts Penn Badgley. In Season 1, Joe masturbates outside Beck’s window. Badgley later confessed he was “surprisingly disgusted” acting it out. Imagine being too creeped out to play your own creepy character. That’s how bad it was.
Lili Reinhart – Riverdale
“Dark Betty” was pitched as edgy, but Reinhart thought it turned into a bizarre sexual sideshow. The storyline felt cheap, the leather lingerie wasn’t empowering, and the cherry on top was a stiff black wig she despised. She’s said bluntly: “I never want to wear that wig again.” Consider it burned.
Joseph Quinn – Stranger Things
Eddie Munson didn’t mind Chrissy hanging out at his trailer. Joseph Quinn minded her death scene. The contorted, bone-snapping horror of Vecna’s kill left him shaken when he saw the finished cut. “There’s no way Netflix will air this,” he thought. Spoiler: they did, and fans still have nightmares.
Jack O’Connell – Skins
Skins made teen drama gritty, but O’Connell says the intimacy scenes left him exposed in all the wrong ways. Filmed without an intimacy coordinator, they were daunting, compromising, and unsafe. He wasn’t alone: co-stars Freya Mavor and April Pearson have both admitted they were terrified. Years later, those scenes still haunt them.

Matt Smith – House of the Dragon
Dragons? Sure. Decapitations? Fine. But sex scene overload? Even Matt Smith tapped out. Playing Daemon Targaryen meant endless lusty moments, and Smith finally admitted, “Yeah — slightly too much, if you ask me.” Basically: less brothel, more battle.

Evangeline Lilly – Lost
Kate started out fascinating. By Season 3, Evangeline Lilly hated how she became a love-triangle ping-pong ball. Worse, she was pushed into a topless scene she didn’t want. She remembers trembling, crying afterward, and vowing never to strip for the show again. And she stuck to it.

Emilia Clarke – Game of Thrones
Clarke went from being a relatively unknown actress to a global star, but her early GOT days were brutal. Young and inexperienced, she found the nude and sex scenes completely terrifying. She’s admitted she didn’t yet know how to say no at the time and felt pretty powerless in the first few seasons. Later, she asserted herself more — but those first seasons remain regrets.

Miriam McDonald – Degrassi
Emma Nelson’s eating disorder arc is one McDonald wishes had been handled differently. Having battled anorexia herself — and losing her sister to it — she felt the show treated it too shallowly. “I just really wish more could’ve been done,” she later said. Sometimes fiction stings because it’s too close to fact.

Blake Lively – Gossip Girl
Serena van der Woodsen was glamorous, messy, and occasionally… a bad influence. Lively’s least favorite moment? A Season 1 scene where Serena gives cocaine to a friend who overdoses. Fans blurred fiction and reality, assuming she was like Serena. Lively hated that, calling the storyline nothing to be proud of.

Angus T. Jones – Two and a Half Men
He grew up as Jake Harper, but by his teens, Angus T. Jones had joined the Seventh-day Adventist church — and turned on the show that made him famous. He called it “filth” and said its crude humor mocked real struggles. His words: “I was a paid hypocrite.” Ouch.
Hilarie Burton – One Tree Hill
For Peyton and Lucas’s first big love scene, Burton was asked to kiss her co-star’s bare chest. She was young, uncomfortable, and cried in her trailer. “It felt dirty,” she later said. Not exactly the dreamy teen-drama memory fans imagined.

Lyle Lettau – Degrassi: Next Class
Sometimes regret isn’t about nudity or awkwardness. For Lettau, it was about principle. A scene had his character Tristan angrily reject the label “gay writer.” Lettau fought back, saying it didn’t fit Tristan and sent the wrong message. His take: people should choose their own labels, period.
