Actor Warwick Davis owes his big break, aged 11, to his paternal grandmother Edith, who heard a radio ad advertising for short people to appear in Return Of The Jedi.
Warwick takes a non-judgemental approach as he researches the family line stretching back from Edith, finding humanity and humour in some uncomfortable stories.
On his maternal side, Warwick is equally open-minded when he finds out about his great, great, great grandfather: a postman who lived a double life.
