Assistir TopFlix. Comedian, actor and ex-English teacher Greg Davies is a lifelong fan of Barry Hines's classic novel A Kestrel for a Knave, the story of Billy Casper training a kestrel as an escape from his troubled home and school life. In this documentary, Greg goes in search of the book's enduring appeal, travelling to Barnsley, where the book was set and where Ken Loach's famous adaptation, Kes, was filmed.
