Timothée Chalamet recently shared details of an unpleasant incident involving Matthew McConaughey during the filming of Christopher Nolan’s Interstellar. On his last day on set, Chalamet discovered an unwelcome surprise in his trailer bathroom, a prank that has since drawn strong reactions online.
Unsettling Experience on Interstellar Set
In a candid joint interview with Variety, Timothée Chalamet recounted how he found a large feces deposit in his trailer’s toilet on the final day of shooting Interstellar. Feeling disrespected, he approached several crew members and castmates to identify the culprit but initially received denials.
Chalamet said,
“I gotta say, my last day on Interstellar, I was sad to be leaving. In my trailer, I went to the bathroom, and there was a huge turd in my toilet.”
He added,
“I felt so disrespected. Like, ‘I know I’m not the star of this movie, but who’s coming in here?’”
Matthew McConaughey Admits to the Prank
When Chalamet confronted the grips and the director Christopher Nolan, Nolan directed him toward Matthew McConaughey, who responded with a mischievous grin. Chalamet quoted McConaughey’s explanation:
“‘In Texas, it’s a coming of age, baby.’”
To this, McConaughey simply described the prank as a “Souvenir.”
Negative Reactions on Social Media
The story sparked immediate disgust online, with many condemning McConaughey’s actions. One widely shared post on X described the prank as “Gutter behavior. Childish and uncouth,” drawing over 1.4 million views. Another user expressed shock, saying,
“???????????? This permanently changed how I view Matthew McConaughey and I’m not even kidding what’s wrong with him.”
Additional criticism focused on the actor’s age, emphasizing that McConaughey was 44 when filming Interstellar. A commenter on Reddit questioned,
“What 44 yo does literal shit like this on the job as a prank and still gets to keep their job?? Oh that’s right…actors. It’s always male actors pulling these ‘pranks’ whether it’s not flushing their bodily waste, destroying another (female) actor’s property (book), etc.”
Voices from the Audience Express Disbelief
I wouldn’t even consider doing that to a relative or close friend, but a coworker that’s like 19 years old and that you barely know???
Another user reacted with incredulity:
Imagine wrapping your final day on an Oscar-winning sci-fi epic and your send-off is… that. Hollywood is wild,
while a further comment added,
why do men do shit like this and think it’s funny.
Understanding the Impact of the Prank
This incident underscores issues of respect and professionalism on film sets, highlighting how pranks can cross boundaries and affect workplace environments. The fact that a senior actor like McConaughey engaged in such a stunt toward a younger co-star has caused discomfort among fans and industry observers, raising questions about workplace culture in Hollywood.
Timothée Chalamet’s openness about this experience brings attention to how off-screen dynamics can shape an actor’s memories and public perception of major productions. Given the backlash, discussions may prompt greater reflection on on-set behavior and the treatment of younger or less established actors in the industry.
