One reviewer here asks how much more drama can be "squeezed" from this "event". I would answer an infinite amount. There will never be too much that can be said or portrayed about the largest act of genocide, torture and madness. To the already copious number of films on the subject, comes The Invisibles, a docudrama, so labeled with names of the two genres that combine successfully to make up this film. I thought the combination worked extremely well. Having the actual photographic footage of Berlin during the war gave the film an aura of authenticity that enhanced it. Also, the interviewing of the survivors, combined with enactments of what they were reporting, also worked extremely well. In fact, seeing and listening to them made watching the film more bearable for me as I knew they avoided the horrific fate that most of their compatriots didn't. The only reason I rated The Invisibles a 9 and not a 10 was because in a couple of instances I experienced some confusion, mainly about who was who. I think there could have been a bit more clarity in this area. Other than that, the world now has another documentation of something that you'd think happens only in nightmares.
