From street urchin to knight of the realm - the story of Norman Wisdom, who used to be one of the biggest film stars in the UK - portraying a man who rarely stepped out of character in public, and whose highly individual comic style hid the private tragedy of his early life.

The actor's life story is told through the people who knew him well - his son and daughter Nick and Jaqui Wisdom, his daughter-in-law Kim, film director Stephen Frears, actors Ricky Tomlinson, Leslie Phillips and Honor Blackman and singer Dame Vera Lynn.
