I'm very much awaiting this. 1960's Congo conflict. The various African conflicts have always been a huge draw to me. Mainly because they were often many-sided, with various ins and outs most people often ignore, Such as Communist Cuba sending many, MANY thousands of troops to fight in the Angola Civil War, the Rhodesian Bush war and the Congo Civil War.
The Wild Geese is a good favorite movie of mine. This looks like it may match it.
