Brilliantly acted by all and an outstanding performance from Benedict Cumberbatch. I was in my early teens when this was going on and really had no idea of the seriousness of the crisis at that time. To know now that two very ordinary, incredibly brave family men played such a crucial part in averting what could have been total devastation was eye-opening to say the least. The way the film portrayed the events was, without being over dramatic, very moving and enlightening. Not one to miss, especially if you enjoy true stories!
