I often find some films about the lives of real people interesting to watch. I have always thought it must be a challenge to portray a person who has walked or is still walking the Earth. You have the burden of whether it is authentic enough or a more sensational exploration. Whatever the case, the question is what are your favourite performances based on real life people? It can anyone from a president, monarch or governor to a saint, dancer or musician. Whatever your choice, please give it.
