Is Hollywood’s new golden boy REALLY a ‘hyper-paranoid diva’? Insiders reveal ‘frat boy’ behavior behind the scenes of Timothee Chalamet’s new movie… and the cruel edict allegedly issued to the crew

If America’s new Hollywood sweetheart is a man, it would be actor Timothee Chalamet.

On-screen, he brims with emotional vulnerability. Off-screen, he is goofy, occasionally shy and, sometimes, deliriously smiley.

‘Timothee! Timmy!’ screamed a crowd of hundreds waiting for a glimpse of him outside the Venice Film Festival’s Sala Casino in September 2022.

Many of them had been waiting three hours in the hot sun.

‘It feels nice to have a Gen-Z star who seems genuinely nice, whom we can all look up to,’ gushed one fangirl.

Indeed, it would… but what if Tinseltown’s sensitive new golden boy is only acting?

Movie industry insiders who worked closely with Chalamet on his upcoming Bob Dylan biopic, ‘A Complete Unknown,’ claim the burgeoning superstar is, in fact, a raging ‘diva’.

And as filming wrapped on the project in June, several crewmembers spoke exclusively to DailyMail.com about the allegedly ‘toxic’ on-set environment fraught with complaints of ‘cruelty’ and ‘frat-boy behavior.’

‘[Chalamet] was hyper-paranoid,’ said a crewmember on the film’s Hoboken, New Jersey set.

‘We were not allowed to make eye contact with him or introduce ourselves.’

In one encounter, Chalamet allegedly flew into a rage and ‘cursed out’ a low-level production assistant who – while snapping a picture of the solar eclipse on April 8, 2024 – accidentally included the actor in a photo’s frame.

A security guard on the production ‘scoured her phone and made her delete all the photos,’ the insider claimed.

Just 20 minutes later, Chalamet reportedly forced the movie’s producers to send a strongly-worded email to the entire cast and crew prohibiting ‘all cell use’ near the leading man.

‘The production assistant panicked that she was going to get fired,’ said the source, who claimed on set security would browbeat anyone who used phones in Chalamet’s proximity, ‘even when using them was critical to aspects of their jobs.’

Additionally, Chalamet allegedly ‘hated when the crew watched rehearsals’ and harbored a particular loathing for ‘stand-in’ actors, who helped the lighting department fine-tune their setup before he arrived for a scene.
