Mark Kermode’s Secrets of Cinema – Monday, BBC Four, 9pm It’s always a cause for celebration whenever Kermode returns with another series of essays examining the recurring themes, conventions and techniques of various film genres. The latest batch begins with British comedies, which can often reveal as much about our national character, obsessions and prejudices than any number of gritty social realist dramas. With characteristic clarity and a wide-ranging selection of case studies, Kermode analyses the ways in which these films tackle attitudes towards sex, race and class. Subjects under review include underdogs vs authority, and the timeless comic conceit of pompous self-delusion. Any programme that allows space for the likes of Carry On Cleo, Theatre of Blood and Chris Morris’ Four Lions is alright by me.
