BBC Two has produced, and placed on the Internet, some Priestley Shorts based on the multi award winning production of An Inspector Calls by the Royal National Theatre and the 1954 film version starring Alistair Sim. The shorts focus on, respectively, Inspector Goole and Mrs Birling and feature Stephen Daldry, the director of the RNT production, together with actors from it talking about their roles.
