The Return of Little Big Man
Thomas Berger wrote The Return of Little Big Man in 1999, 35 years after he wrote the novel Little Big Man. It's a great book and takes up the story from Jack leaving the LBH and walking into Deadwood.
I wonder if anyone has pitched The Return of Little Big Man? It would make a great film if done right. Dustin Hoffman is way too old though to play a 35 year old Jack Crabb.
