5. 'Dallas Buyers Club' (2013)
Like many Oscar-winners, McConaughey has peaked higher than the performance that netted him a statuette. But that shouldn't diminish his evocative portrayal of Ron Woodroof, a homophobe who contracted HIV in the 1980s and decided to make a buck off his fellow sufferers. Best when fighting off inspirational-drama platitudes, Dallas Buyers Club focuses on a flawed man who begrudgingly grew a conscience once his life was threatened. McConaughey never lets you forget that Ron is a stubborn old bastard — and makes you respect the guy anyway.
