Jim Carrey recently said that working on The Grinch was a nightmare that still gives him “goosebumps” because it was like “being buried alive every day.”

Carrey was so weary that he almost dropped out of the 1998 film The Grinch.

On The Graham Norton Show, the comedic veteran confessed openly that donning the monster’s costume felt like being buried in layers of fur, and that it was really disturbing.

“It was like being buried alive every day. I went back to my trailer and put my leg through the wall and I told [director] Ron Howard I couldn’t do the movie,” the actress said.

He also revealed that producer Brian Grazer recommended enlisting the help of the CIA.

“[He decided to] hire a gentleman who was trained to teach CIA operatives how to endure torture. And so that’s how I got through The Grinch! It was quite hilarious,” Carrey explained.

He further stated that the CIA instructed him to eat everything he could to cope with the agony and to smoke smokes ‘as much as he possibly could.’

However, if Carrey tried to smoke, his costume would function as a huge impediment because he didn’t want the furs to catch fire.

“It was horrifying! It was horrifying!” he remarked. ” In the end, he had to keep reminding himself: “It’s for the kids, it’s for the kids, it’s for the kids, it’s for the kids.”

He did, however, reveal the one soothing music that got him “through it all,” referring to the Bee Gees.
