I saw the original version of this movie when I was a little kid. I was very intrigued by it, but I haven't seen it in ages. I was at the video store yesterday and I noticed that there was a remake from 2002, with James Caan and Lisa Bonet. So, I rented it.
I thought this version was interesting, but not quite as gripping as the original version. Whether or not that is due only to age difference, I'm not sure.
Anyway, I think I need to buy the book.
