Quite often directors & producers are attempting reconstructions of events which happened in the past. It maybe a historical documentary in which we need to see an old building or a dramatic event. It may be part of a current affairs documentary about a disputed event, in which case we can reconstruct what we know from peoples testimony. It maybe a drama where the production can only afford so many extras and set design and we are sometimes asked to enhance things. NB: When viewing some of the examples below, you may need to be patient because of the large file sizes involved.
