Clint Eastwood is 88 years old and has a successful career spanning over six decades. During that time he has proved to be one of America’s most bankable box office stars and established himself as an actor and director of note among his peers. If The Mule turns out to be his swansong, then it is certainly a fitting end to a prestigious career. Because in many respects The Mule is a distillation of many of the themes and concepts, we’ve seen in previous Eastwood movies such as Gran Torino and The Unforgiven. Perhaps the core story of an ageing man trying to reconcile himself to a modern world and make peace with it, is in some way Eastwood commenting on the movie industry himself. It is very much his film and his performance underpins the proceedings.
