The Shaun of the Dead funnyman has signed a deal with Hodder & Stoughton to release Truths, Half Truths and Utter Bulls**t, a "dark, exhilarating and movingly honest" memoir which covers his "extraordinary" life story, according to his publisher Hannah Black.

Frost says, "If I'm going to tell the story of a life, my life, then I need to tell it warts and all. If the tale is too saccharine sweet then what can the reader take away from it? What do they learn about you? I'm writing everything down. The s**t, the death, fun, naughtiness, addiction, laughter, laughter, laughter, some tears and lots of love and happiness. That to me is a better reflection of a human's life."

The book is due to be released in October (15).
