Mum

Comedy, the late, great Tony Hancock would often tell his dinner guests, was simply “frustration, misery, boredom, worry – all the things people suffer from”.

This may go some way to explaining the success of a crop of deceptively simple, single-camera comedy-dramas that have all but replaced our more traditional idea of the sitcom in the television schedules.

If anyone ever doubted that comedy and tragedy go hand in hand, look no further than the much-garlanded BBC Two sitcom, Mum, starring Lesley Manville as Cathy, a late-­middle-aged mother coming to terms with the death of her husband.

Making a TV audience laugh is among the most difficult skills for any screenwriter to learn, but to make them laugh one minute and almost cry a few moments later is the hallmark of a very special talent.
