I watched Capote last night (thanks, Pam for the loan!).  If you've not seen it, rent it...now.  The story covers Truman Capote's life during the time he wrote In Cold Blood, the story of the Kansas murder of 4 family members.  You may think it to be just a biopic but the acting and cinematography makes it so much more.  The extras on the DVD had interviews with the producer, director, cinematographer, etc and it was fascinating to see how each detail was taken care of.   They ended up with a truly great film.

PS - Michael, if you read this, Harper Lee is a character in the film.  Seems that she and Capote were childhood friends.
