Jim Carrey has said that he never set out to do a Dumb And Dumber sequel.

The follow up – co-starring Jeff Daniels – is being released two decades after the 1994 film.

“I was never planning on doing a sequel, but people never left me alone,” the star said.

“They just kept after me, wanting to see another one, and then I watched it 10 years ago. I’d seen bits and pieces a number of times, but this time, I sat and watched it and was laughing. I couldn’t believe some of the stuff we did.

“I was like, ‘Gosh, I really like these guys, maybe the world needs them’. Plus the world leaders were calling me,” he joked. “They said, ‘There’s unrest, we need your help’.”

The 52-year-old admitted he put in a “lot” of input on the script for the jokily titled Dumb And Dumber To.

“I can’t keep my hands off stuff and come up with as many insane things as I can possibly think of. I just spew and they go, ‘Inappropriate… Appropriate’,” he said.

Dumb And Dumber To is released on Friday, December 19.
