Bruce Almighty star Jim Carrey has written a children’s book about "a scared little wave"

The 51-year-old grandfather told the Press Association why he wrote Roland Rolls, the story of a little wave who's frightening of dying when he eventually hits the beach.

He says: "I wrote a children's book. Because I just think, I want to be part of special moments for people and to me, there's nothing more special than the moment before bed when you're reading a story with your kid.

“That's one of those moments where it's just kind of a little slice of heaven when you're reading the story".

Carrey, who has a 25-year-old daughter named Jane Erin, added: "It's a story about a wave named Roland that is afraid that one day he's going to hit the beach and his life will be over.

"But when he gets deep, he's struck by the notion that he's not just a wave - he's the whole big wide ocean. And it's kind of a metaphysical children's story, which deals with a lot of heavy stuff in a really childish way.

“And you know, I think it's going to be good for kids and parents will go to bed feeling safer.

"I didn't choose it, it just came. It's just how I feel. We spend our lives caught up in the minutiae of these little emotional things that happen and it's like we're waves in the ocean."

Carrey, who appears opposite Steve Carell in the comedy The Incredible Burt Wonderstone, also revealed that he split with his Tipperary girlfriend, 26-year-old make-up artist Cathriona White recently.

According to The Irish Independent, he said: "I did go out with an Irish girl.

“We're not seeing each other anymore. But she is lovely."

The Incredible Burt Wonderstone opens in cinemas on March 15.
