It is claimed that actor Cornel Wilde was so technically unprepared, financially underfunded and physically unwell that reinforcements had to be brought back from the UK following their return from filming Zulu the previous year. Apparently their local knowledge and expertise was much needed and presumably appreciated when the actor's health was restored and he took up the directorial role, as well as that of the near naked runner. It is an extraordinary film featuring Wilde being chased by natives across African plains amidst much local wildlife activity. Much of the animal footage is stock material but fits in well enough and overall we get an impressive vision of ruthless and desperate animal survival contrasted with the dastardly acts of ivory poachers and slave trade apologists. The film is not overlong and just about keeps going despite the actor/director not being particularly charismatic or earning of too much of our sympathy. There is just enough interchange with the Africans and their ways, helped enormously by the spectacular landscapes to make this a worthwhile watch.
