It's 25 years since Madonna first came to the attention of the world, and since then she's barely been off the chart, out of the papers or even come close to dropping off the public's radar. And as her longevity and quality of work furnish Madonna a respect that few artists ever achieve, even in an age when the average 'celebrity' is a first rate nonentity, she continues to shine brightly, sparkle incandescently and impress almost everyone. This is a documentary film which concentrates on this extraordinary woman's work as a dancer, a performer and an actress. From her astonishing music videos to her staggering live shows, and a reassessment of her often unfairly criticised film career, this programme looks again at how she has entertained us for more than a quarter of a century to an extent few if any have ever come close to matching.
