Oppenheimer (out Jul 20) will be spoken about for a long time.  Representing a slight pivot for Christopher Nolan (better known for action-thrillers), it’s a brilliant biopic about the American scientist credited with inventing the atom bomb in the 1940s. The editing sets a frenetic pace, the music is intense, and Cillian Murphy’s lead performance is extraordinary. It’s rare for a biopic to capture so many competing angles of a single individual. Grade: A.
