'There's definitely pressure when you're adapting JK Rowling' - the stars and crew of the BBC adaptation of JK Rowling's first Cormoran Strike detective novel discuss the challenges of bringing a much-loved writer's work to the screen.

Star Holliday Grainger (Robin Ellacott) explains how she was cast, while co-star Tom Burke (Cormoran Strike), talks about preparing to play a detective with physical and psychological injuries from the war in Afghanistan. This major new adaptation is produced by JK Rowling’s production company Brontë Film and TV.

This event was filmed at London's BFI Southbank in August 2017 with actors Tom Burke and Holliday Grainger, director Michael Keillor, writer Ben Richards and executive producer Ruth Kenley-Letts.
