In Darkest Hour, director Joe Wright and writer Anthony McCarten are both firmly in their wheelhouse. Both men are big on these kinds of historical period pieces, so they certainly know what they are doing here. While it is tempting to consider Darkest Hour a companion piece to Cristopher Nolan’s Dunkirk earlier this year on account of the similar subject matter, it is crucial to recognize that Darkest Hour approaches this story from a more singular perspective, focusing on a kind of character study of the great Winston Churchill instead of a more all-encompassing view of heroism. Fortunately, Gary Oldman turns in one of the greatest transformative performances of his career. Thus, though Darkest Hour is a fine film Gary Oldman is easily its centerpiece.
