Because of his long run as James Bond it's all too easy to forget Roger Moore's other films. This action drama from director Peter Hunt (who also directed a great 007 film) and adapted from the novel by Wilbur Smith is a fantastic movie. Set in South Africa during the apartheid years it was potentially controversial in its depiction of camaraderie between white bosses and black workers although the narrative does have a racist baddie. In the Sonderditch gold mine owned by a wealthy millionaire - superbly played by a curmudgeonly Ray Milland - and run by his sly son in law (Bradford Dillman) the handsome and unorthodox Rod Slater (Moore) is promoted to lead an exploration into a deep chamber believed to shield water but a new report suggests hides a rich gold seam. Moore is having an affair with Dillman's wife, the sexy Susannah York, and doesn't realise he is the foil in an international conspiracy to flood the mine and drive up gold prices. The film is action packed, exciting, tense involving mining disasters, heroics, sex and devious plots and it's all round great entertainment. A great little film which is well worth seeking out if you haven't seen it.
