This revealing documentary charts the life and career of the current reigning queen of British comedy, from live stand-up to multiple award-winning sitcom writer-star and serious dramatic actor.

The 6'1" funny-woman's awkward and clumsy persona, with beautifully executed comedy pratfalls, has reinvented slapstick for the 21st century. But it is the warmth within those performances that has won her millions of fans since she burst onto our screens.

Although many think of Miranda as a new arrival, it was far from an overnight success story for the boarding-school girl from Hampshire. She was inspired to entertain after seeing her hero Eric Morecambe on TV.

Making an annual pilgrimage to the Edinburgh Festival, she gradually honed an act exaggerating her own diffident personality. The hard work paid off by the early 2000s, as she won various cameos in shows such as Smack The Pony, Not Going Out and Absolutely Fabulous before landing the self-penned, semi-autobiographical eponymous sitcom which transformed 'Miranda' from character comedian to comedy superstar.

By then in her late 30s, the plaudits came thick and fast, notably multiple British Comedy gongs, not to mention a more recent win at the 2013 National Television Awards for her accomplished dramatic turn as Chummy in the much-loved BBC period drama Call The Midwife.

Her autobiography made her a best-selling author, her live show sold out London's huge O2 arena, she made a splash with her first ventures into Hollywood alongside Melissa McCarthy and Jude Law. This late developer is going to slow down any time soon.
