I too love that movie Jeremiah Johnson!  One of the best ever!  You guys are awful, now I have a couple books I have to go buy to read... I'm one of those that if a book is really good, I won't be able to put it down and I'll be up at 2:30 AM still reading like someone else did her as well!   
I named my son after Jeremiah Johnson and his name was Jeremiah David (for the middle name after me).  It pleased both me and my wife.  She looked at it with a biblical perspective of Jeremiah from scripture while I was pure mountain man on my side!
