Just in at the Nichols Library:  the first round of Oscar-winning movies on DVD, new fiction for a variety of tastes and thought-provoking stories from real life.  Gary Oldman got the best actor nod for his portrayal of Winston Churchill in “Darkest Hour”.  Oldman “brings Churchill vividly to life”, but then, Churchill handed the actor some of the best lines in history.  The award for best actress went to Frances McDormand, who plays a woman who calls out her police chief for not doing his job by renting the titular Three Billboards outside Ebbing Missouri.  “McDormand’s sorrow, festered into rage, is the emotional epicentre of the film”.
