There's a bit of a wait for this one but it's up for pre-order already on Amazon US and UK.
A search for 'The Philosophy of Clint Eastwood' on Google gave an interesting result here which was the editors (Brian B. Clayton and Richard T. McClelland) calling for essay papers on the subject. Here's the main text from the link:
The Philosophy of Clint Eastwood will consider Mr. Eastwood’s body of work as actor, director and, in recent years, composer in relation to philosophical concerns and approaches. It will introduce general readers and intelligent non-specialists to the story lines, approach to filmmaking and film acting, and philosophically relevant themes of Mr. Eastwood’s storied career in television and movies. The volume will be proposed for the University Press of Kentucky series in the Philosophy of Popular Culture.
Essays may address particular movies, groups of movies or topics that bridge multiple movies, for example: force and authority, violence and society, transplanting the Western hero into contemporary society, propaganda in times of war, jazz style and filmmaking, personal
responsibility and choice, ethics and vengeance, genre revision, law and order in the old West, ethics of death and dying, hardboiled detectives, issues of faith and reason, role of emotions, music and affect, crises in psychological development, re-envisioning history, and dealing with personal loss.The essays had a due date of June 1, 2010 so looks like they've taken a while to edited it
