A friend worked on a documentary for Arte, about how people experienced the end of Communist rule.
It is free, online, on the arte website.
Here is the link to the first episode of six, of Adieu Camarades (in French, for the moment).
There is an interactive web documentary archive that goes hand in hand with the film but which is allows more freedom of interpretation. It is a tapestry of portraits of ordinary people with fascinating communist pasts using original postcards from the period as a springboard for their accounts.
