IT was a stunt Jim Carrey himself could find cringe-worthy.

During the Czech Lions film awards ceremony in Prague, basically the Czech version of the Oscars, organisers were conned into giving an impersonator of the comedian the star treatment.

The fake funnyman not only managed to score an invite to the film festival, but was invited on stage, given an awkward applause by an audience who didn’t exactly seem fooled, and showered in glitter.

The host, Lucie Vybornia, had initially insisted to a local paper that “it was really him”, but organisers were eventually forced to admit they had been duped.

The impostor had allegedly received a note they received from the Canadian actor’s managements saying he wanted to attend the ceremony, but they didn’t realise they had been had until after featuring him during the Czech film industry’s night of nights.

Despite the con man bearing very little resemblance to the Dumb and Dumber star, a spokesman for the Czech Lion Awards said “nothing indicated it was a ruse”.

Film director Jan Sverak apologised for the hoax, The Independent reports.

“We have become very likely the target of a very elaborate hoax,” she said.

“It was not my intention, but I must salute someone’s perfect game in managing to con us.”

The real Jim Carrey was last seen in Hollywood at a pre-Oscars party over the weekend. It is unknown what has become of fake Jim Carrey.
