Josh Brolin shared a hilarious behind-the-scenes story from The Goonies in his new juicy memoir From Under the Truck.

The 56-year-old actor revealed how his unfiltered excitement during the filming of the 1985 blockbuster inadvertently derailed a key scene: the first reveal of One-Eyed Willy’s pirate ship.

Director Steven Spielberg had carefully planned for an authentic, surprised reaction from the young cast—Brolin, Sean Astin, Corey Feldman, Martha Plimpton, and Ke Huy Quan—who were playing a group of friends on a quest for hidden treasure. 

The actors were submerged underwater, waiting for the cue to rise and see the ship for the first time.

When Brolin surfaced, however, he couldn’t contain his excitement, shouting, ‘Holy SH**! F***!’ instead of the more subdued reaction Spielberg had hoped for. 

Spielberg immediately called ‘CUT!’ and reminded Brolin, ‘You can’t say f*** in this movie!’

‘I wasn’t acting. It was me saying this. Organic. I’d never seen anything like this,’ Brolin wrote. 

‘It was bigger than life, bigger than ,y teenage imagination would allow me to swallow.’

He added: ‘The kids all laughed, and even though I knew I’d messed it up, I laughed too. I don’t know, man. They should’ve warned me.’

Brolin also opened up about feeling out of place while filming The Goonies, which marked his acting debut at just 16 years old.

He recalled being driven to an airport with his guardian, heading off to shoot the film for several months. 

It was there that he met his fellow cast members—Astin, Feldman, Quan, and Plimpton—and the rest of the production crew.

‘I can’t help but feel I’ve done something good for the first time in my life,’ Brolin wrote about the moment at the airport, ‘but also it might be a mistake that I’m here.’

The actor reflected on how surreal it felt to be among his accomplished colleagues, many of whom had already starred in other projects.

The actors were submerged underwater, waiting for the cue to rise and see the ship for the first time and when Brolin surfaced, however, he couldn’t contain his excitement, shouting, ‘Holy SH**! FCK!’ instead of the more subdued reaction Spielberg had hoped for

Spielberg immediately called ‘CUT!’ and reminded Brolin, ‘You can’t say f*** in this movie!’

‘It’s all very strange that I’m here with them, a part of it,’ he shared. ‘I’ve never been part of anything other than with people who nobody else wanted to be a part of.’

Brolin’s new memoir is filled with deeply personal stories as well, including the tragic loss of his best friend at a young age and his battle with substance abuse that spanned over a decade.

He also recounts a pivotal moment from 1981, when he took acid for the first time with friends, leading to a harrowing 12-hour trip that marked a turning point in his life.

Brolin also opens up about how Barbra Streisand was a key figure in his recovery, offering much-needed support during one of the toughest times in his life as he fought to get sober.
