Sheen, Estevez to write bio together

Martin Sheen and son Emilio Estevez have announced plans to write a joint memoir.

The project, titled Along the Way, is scheduled for release in February 2012, in times for Father's Day, reports Gossip Cop.

The book is billed as a "dual memoir told in the alternating voices of father and son" about family, friendship and faith.

In a statement, Estevez said: "I'm so happy to be working on this unique project with my father. We're both fathers and sons, we're neighbours and activists, and we hope that our story will communicate an essential message for our times - Film is an illusion. Fame is ephemeral. Faith and family are what endure."

Sheen and Estevez shared the screen in the films The War at Home and In the Custody of Strangers. Sheen also starred in Bobby, directed by Estevez.

There is no word on how or whether Charlie Sheen, Martin's other son and Estevez's brother, would be depicted in the book.
