I just finished reading the bios of the stars of the 80s show Moonlighting.  Cybill Disobedience: Cybill Shepherd's memoir of her 35 years in show business and Bruce Willis: The Unauthorized Biography by John Parker.  The first was dishier and more interesting because Cybil obviously is more into self-disclosure than Bruce.  Bruce was not interviewed for the biography but the book includes a good filmography for film buffs and Willis fans alike.

I recommend both.  They're quick and easy reads that shine a little light into the drama and mystery that surrounded the giant tv megahit in the late 80s.
