Former Doctor Who star David Tennant, will be narrating a new documentary for

BBC Two.  

The actor, aged 38, will do the voice-over for Karate Kids, part of a six-part BBC2

series focusing on extraordinary children.

Karate Kids is part of the My Life season and follows a group of disabled children

who learn adapted martial arts skills in a bid to improve their movement and

confidence. The episode will air on 13th March at 11:30am on BBC Two.

The BBC press office says:

My Life, CBBC's single-subject observational documentary strand, continues with

Karate Kids, which follows three disabled friends, Suleyman, Francis and Tim. The

friends work with martial arts master Glenn, who is using Sanjuro, his own unique

blend of martial arts dance combat, to help improve their movement.

The three friends all attend a school for children with physical disabilities and

associated special educational needs in London. The work Glenn does aims to give

them self-respect, self-discipline and focus, as well as improved confidence and

fitness.

Buoyed by the martial arts classes, Tim seems to benefit more than most. He has

never been able to move or communicate unaided, and relies on his mum and best

friend Francis to get his thoughts to the outside world.

Karate Kids follows him through a very busy school term which sees him being

nominated for a national award from disability charity Cerebra, run for Class

President, and experiment with new laser-eye computer technology which may offer

him a voice of his own and a glimmer of independence for the first time.

The remaining films in the My Life strand are My Dad In Prison, which examines

what it is like to be a child with a father in prison and follows the work of an

innovative new prison homework club; and Children Of The Road, which follows a

group of Irish traveller children at one of the biggest traveller sites in the country.
