Here's the link to a site with some of the only online information I could find about the first two 'Mad Max' novels:
I've been meaning to get ahold of the 'Escape From New York' and 'The Dark Crystal' novels. Too bad there aren't novelizations for 'Escape From L.A.' or Ridley Scott's 'Legend'.
As far as I can tell, there is no novelization for 'The Hitcher'. Which is too bad, it would be such a cool tie-in to own, considering that the 'The Hitcher' is one of the top thirteen best horror films of the 80's (according to both Fangoria and myself). So is 'Near Dark', but that doesn't have a novelization either, nor does 'Henry: Portrait of a Serial Killer'.
I looked up "Southern Comfort" on Amazon, and there was a book by that title published the same year as the movie was released. I have no idea whether or not it's actually a novelization, as I couldn't locate any cover art when searching Google Images, and there weren't any copies for sale on eBay. Couldn't find any information on the plot of the book or its origins either, just the authors and the year of publication. Amazon did not even list the publishing house, which is NOT a normal thing for Amazon! But I did find out the publisher from a different online bookseller.
Here's the info I dug up:
