Kirsty Young's castaway is the actor Warwick Davis.

His career began thanks to his grandmother who heard a radio advert calling for short people to be in the latest of George Lucas's Star Wars films.

Born with Spondyloepiphyseal Dysplasia Congenita (SED), a rare disorder of bone growth which results in dwarfism, the view of his doctors was that he'd be wheelchair bound and unlikely to live beyond his teens. Now in his mid-forties, he is married with two children of his own.
