Mat Horne thinks the 3-D aspect of 'Horrid Henry' was "right" for the film.

The 'Gavin & Stacey' actor - who stars as the titular character's dad in the family movie, which is based on children's books and a TV series of the same name - said the visual format was required because the motion picture is aimed at children.

He told BANG Showbiz: "One reason I did this film is because I wanted to do something in 3-D. I think the style of the film complements the narrative itself because of the audience we're pitching for.

"It seemed sort of right for the film to be in 3-D considering the nature of Henry and all the things he gets up to."

The movie - which features Henry playing pranks and tricks on people in an attempt to avoid doing his homework - has a star-studded cast including 'Addams Family' actress Anjelica Huston, 'Gosford Park' actor Richard E. Grant and comedian Jo Brand, with Theo Stevenson playing the titular role.

Girls Aloud singer Kimberley Walsh - who has previously appeared in 'St. Trinian's' and 'Britannia High' - stars as Henry's overactive cousin Prissy Polly, who spends most of the movie looking after a vomiting child - and Mat explained she was "brilliant" as an actress.

He added: "Kimberley was lovely. She was brilliant and she had quite a difficult job because she had to handle the baby all the time. She's a very down to earth girl, she's very normal.

"I think with somebody as talented as that, you've got to accept she can do various things."

'Horrid Henry' is set to be released in the UK on Friday (29.07.11)
