Yes, I also wonder why there isn't a really good rev-related film yet !
Actually many major revolutionaries shared with Antoine this kind of sensitiveness (which has much to deal with a well-defined specimen of narcissism !), but I see the so-to-say "dionysiac" only in him... Hopefully some director will notice it and think about a wonderful drama :)

No, I didn't read it. I have to admit, I don't know Collot very well. Though I am sure he was very, very interesting his own way. As you already know, I rather prefer his friend Billaud - and often think of writing a screenplay for a film about his incredible life ! One about Collot would be a good idea too, nonethless...
