CAGE fighting twins from Huddersfield are set to star in a TV documentary with actor Danny Dyer.

Dyer is well known for his ‘Cockney hardman’ films, including Mean Machine with ex-Leeds and Wimbledon player Vinne Jones, and The Football Factory, a movie about Chelsea and Millwall hooligans.

But the 31-year-old east Londoner is also famous for presenting gritty documentaries including, The Real Football Factories and Football Factories International on TV channel Bravo.

Last year he launched a new series ‘Danny Dyer’s Deadliest Men’ that sees him venturing into the dark depths of the British underworld, hunting down some of the most notorious and feared men in Britain today.

For the second series Dyer headed north to meet the Huddersfield-based twins Ian and Dave Butlin and experience for himself what it takes to be a hard man.

Ian, 29, a promising boxer before switching to cage fighting five years ago, said Dyer had no idea what he was letting himself in for.

He said: “When we first met him we were going hunting.

“He didn’t know anything about it and then he saw us coming towards him dressed in black.

“I had a rifle and my brother a pistol and he didn’t know what was going on.”

Ian said Dyer had stayed with him at his Lindley apartment for a week in the lead up to an international cage fighting tournament in Japan.

He said: “He followed us as we trained and did all the stuff that we do and got to learn all about how we grew up boxing and fighting.

“He came high-diving with me.

“It’s something I started doing to get over my fear of heights.

“He also had a fear of heights so it was tough for him.

“He’s a good guy, he got involved, the guy did everything that I was doing.

“He made himself sick cardio training with me, so he definitely got our respect.”

Ian Butlin was a promising boxer with the Rawthorpe club before switching to cage fighting five years ago.

Cage fighting is a hybrid of boxing, wrestling and martial arts and has been described as barbaric. Contestants are allowed to punch, kick, wrestle, knee and elbow each other into submission.

Ian, a former Lindley Junior School, Salendine Nook High School and Greenhead College student, became an instant success at the sport, winning titles at home and abroad.

His twin brother, Dave, has also boxed and competed in cage fighting and is the head coach of the England cage-fighting team.

Younger brother Andy is a professional boxer.

He recently notched up another victory to make it six wins from 10 professional points by outpointing Leicester’s Simon Fleck in Bolton.

Dyer himself is enjoying his film and TV lifestyle.

“There’s so much I want to do, it’s hard to put into words. I just feel like I’ve just had a taste of what I want to do.’’
