There's a movie coming out called "Bernie" starring Jack Black and Matthew McConaughey based upon this fascinating 1998 Texas Monthly article about the murder of a wealthy widow in Carthage, Texas. This month's Texas Monthly has an article (I haven't read yet) about how for over 10 years they've been trying to turn that dark and grisly story into a comedy. They've finally done it.
And if you read the original article, you'll want to visit this site afterwards. It has pictures.
