"Darkest Hour" stars Gary Oldman in the true story of the events of Sir Winston Churchill and his involvement in World War II. Since this movie came out in November and received a nationwide expansion in December, you know what that means: potential Oscar bait. This is a good, but not great, interpretation of one of the 20th century’s most prominent figures. Oldman stars as Churchill and as the movie begins, he’s been called on by Parliament to succeed Neville Chamberlain as prime minister of Great Britain.
