Has Jim Carrey been cloned? And other celebrity conspiracies

Hollywood star Jim Carrey is known for some huge box office hits like The Truman Show and Ace Ventura but his most recent appearance on the red carpet has been making headlines.

People on socials were quick to point out an apparent change in Carrey’s appearance, and conspiracy theories about a body double and the actor being cloned went viral.

So where did the conspiracies start? BBC Bitesize Other Side of the Story has whipped off the mask to look at these ssssmokin' rumours.

Where did the Jim Carrey conspiracy theory come from?

The conspiracy theories emerged after Carrey accepted an Honorary Cesar Award during the 51st César Film Awards in Paris on 26 February. He delivered his speech entirely in French.

Some people online said they thought Carrey looked different to the last time he was pictured and pointed to previous comments he's made, including about retirement and enjoying life out of the spotlight.

TikTok users have shared clips of him saying “If I ever shave my face again, you’ll know” on the Jimmy Kimmel Live! show in 2017. He had a beard at the time - but was clean shaven when he appeared at the Césars.

Others felt the comments he made to reporters at the event were significant. Videos showed the actor saying "My favourite funny face is the one I'm wearing right now". One TikTok user said: "When has Jim Carrey ever not made people laugh? Those reporters were silent".

The make-up artist Alexis Stone has also shared a post on Instagram appearing to suggest that they impersonated the actor. It includes the caption "Alexis Stone as Jim Carrey in Paris", photos of Carrey and an image of a mask, wig and fake teeth in a hotel room, with the Eiffel Tower seen from the window.

Stone may just have been joining in with the rumours and there is no evidence that anyone was in fact posing as Carrey.

Always ask if information has come from a credible news outlet and consider if it’s being used for clickbait.

What is a conspiracy theory?

A conspiracy theory is the belief that there are secrets we don't know about. Often people will say they're planned by powerful groups that are shrouded in mystery and influence key events.

They are appealing because often, they say something that people want to believe, or we feel that it makes us ‘in-the-know’ on something others aren’t aware of.

They can be influential and spread really quickly, thanks in part to social media.

Some are harmless but they can also lead to more dangerous misinformation or disinformation, known as fake news, to spread online - and perhaps even go viral.

Why do conspiracy theories like this spread?

Conspiracy theories and fake news are appealing because they often say things that people want to believe, even if they don't seem logical. Celebrity gossip is also something people love to share with friends and family.

In this case, Jim Carrey rarely makes public appearances or gives interviews, adding to an air of mystery around him. There is no evidence that the actor has changed his appearance or that he was not the person at the event.

Carrey’s previous film roles may also have been a contributing factor. Some of his biggest hits have been about people that aren't as they seem (The Truman Show), and hiding behind a mask to take on a new identity (The Mask).

What has Jim Carrey said about the conspiracy theory?

Carrey hasn't said anything official in response to the conspiracy theories. However in a statement sent to Variety - a trusted source of information about the film industry - Gregory Caulier, general delegate of the Césars, said it was a “non-issue”.

Other celebrity conspiracy theories

Carrey isn’t the only star to have these sort of theories spreading about him - but again there is no real evidence that any of them are true.

One about noughties pop-punk star Avril Lavigne claimed that the “real” Avril died after the release of her 2002 debut album, 'Let Go', and was replaced by a lookalike named Melissa. Avril herself has responded to the theories, telling an Australian radio station that she thought rumours of her replacement were "weird".

Paul McCartney has also faced speculation that he died and was replaced by a lookalike, while some fans of nineties rapper Tupac have claimed that he faked his own death in 1996.

When you see conspiracy theories like this online, it's important to think critically. Don't believe everything you see, hear or read, and make sure you use reliable sources to help verify the things you've seen on the internet.

Posts that carry misinformation often go viral because they contain images and stories that are exaggerated and outrageous to deliberately hook our attention.
