Sheen and Estevez penning memoir
Martin Sheen and his son Emilio Estevez are sharing their stories in the same book.
The actors are working on a joint memoir, titled Along The Way, to come out in the US on Father's Day next year.
Publishers Free Press said the book would explore "the inner and outer stages of the journey of a father and son," including the upcoming movie The Way, in which The Breakfast Club star Emilio directs his father.
The film sees The West Wing star Martin play a Californian man who completes a European pilgrimage started by his late son - played by Emilio. During his travels, he encounters a series of international characters on the road, including an Irish author played by James Nesbitt.
