Kristin Scott Thomas and Gary Oldman in Darkest Hour.

In what amounts to a much-wordier companion piece to Dunkirk, Gary Oldman disappears into the role of Winston Churchill in Darkest Hour.

The movie starts shortly before Churchill takes over as prime ministerโ€”a controversial choice to lead who is facing a lot of opposition, including a skeptical King George VI (brilliantly played by Ben Mendelsohn). The film chronicles Churchillโ€™s speeches (transcribed by personal secretary Elizabeth Layton, played winningly by Lily James) and his strategizing, leading up to him gaining Parliamentโ€™s support in not seeking peace with Hitlerโ€”and pledging all-out war.

Director Joe Wright (Atonement, Hanna) always makes great-looking movies, and this is no exception. Oldman is virtually guaranteed an Oscar nomination as Churchill. Itโ€™s not a role you would think he was born to play, but excellent makeup and prosthetics make his transformation completely convincing. This isnโ€™t just a guy working through a bunch of stuff on his face; Oldman inhabits the role in a way that makes you forget the makeup. Kristin Scott Thomas does career-best work in the small but pivotal role of Clemmie, Churchillโ€™s extremely tolerant wife.

Darkest Hour is one of the better-acted films of 2017. Much of the running time deals with behind-the-scenes maneuvering regarding the events at Dunkirk, and itโ€™s because of this that Darkest Hour plays great in a double feature with Christopher Nolanโ€™s action-pic take on the same event.

Darkest Hour is playing at theaters across the valley.
