Rebecca Hall gives a stunning performance as Christine Chubbuck, the newscaster in Sarasota, Florida who, struggling with depression, committed suicide on air during a live broadcast in 1974. While the film’s ending is tragic and inevitable, its story is both a sensitive portrait of a disturbed personality and an incisive, even satirical, depiction of the treatment most women encountered in a 1970s newsroom. The supporting players are terrific, including Michael C. Hall as the charismatic anchorman to whom she takes a shine, Tracy Letts as Christine’s blustering boss, and Maria Dizzia as the camerawoman who could become her friend. This riveting drama is also vivid and humorous in its 70s atmosphere and details. Rated R. With J. Smith Cameron, Tim Simons, John Cullum. Writer: Craig Shilowich. Director: Antonio Campos. (US 2016) 120 min.
