Nisha Ganatra’s topical dramedy Late Night (B) is a splendid showcase for outstanding performances by Emma Thompson and Mindy Kaling, a gifted comedic actress who also wrote the deeply observant screenplay. Thompson portrays a fictional long-running television show host (think Jay Leno by way of Ellen DeGeneres by way of The Devil Wears Prada), and Kaling plays the overeager first female writer to join the venerable late night show’s creaky comedy writing bullpen. Although the fish out of water workplace dynamics are fairly familiar, the fresh feminist take on the art of fully revealing oneself in one’s career makes the film poignant and powerful. Amy Ryan gives a commanding performance as the studio chief, and John Lithgow is effective as Thompson’s supportive spouse. Thompson is the main attraction here, in amazing acerbic form. It’s especially fun as the fiftysomething comedian finds her voice again by doing stand-up in front of a non-studio audience. This high-brow but accessible film has a great message about being authentic and is warm and witty in telling its tale. It’s a nice antidote to summer action fare and deserves to find a wide audience.
