Ah, so this explains why the film adaptation has been stalling for so long. Word on a new, more faithful take on the book with Frank Darabount writing and directing has been circulating for probably almost a decade now. I still have a print of the book with a section that talks about Darabount's efforts (at which time Mel Gibson, pre-Passion of the Christ, was slated to star).
The Truffat film wasn't really an accurate portrayal of the book. I was looking forward to Darabount's allegedly more faithful depiction. Oh, well. Maybe someday soon.
Also, FWIW, I love Equiliberium. I saw it as a video rental with low expectations but came out wishing I had seen it on the big screen. Yes, as stated before, it's a bit derivative but it's still done in a thought provoking and entertaining way.
