John Grisham books are totally not my thing, so there's nothing I can say here- snarky, learned, or otherwise (if that's not a set-up for my scourging in Talkbacks, I don't know what is).
But if you count yourselves amongst the legion of Grisham followers, the info below might be of interest to you.
Hunt Lowry (A TIME TO KILL, THE LAST OF THE MOHICANS) and Mark Johnson (CHRONICLES OF NARNIA, GALAXY QUEST) are getting ready to adapt Grisham's 1999 novel THE TESTAMENT - which has awaited bigscreenification for quite a while now.
In the novel, a billionaire defies his greedy relatives and leaves his $11 billion fortune to a mysterious illegitimate daughter doing charity work in the Brazilian wetlands. A down-and-out lawyer helps her battle her relatives over the fortune.
The last time Grisham ended a self-imposed moratorium on selling a book to Hollywood, his first novel, "A Time to Kill," went to Warner Bros. and New Regency in a near-record $6 million deal that led to a 1996 hit movie on which Lowry was a producer.
