You know a film’s controversial when a judge demands all its copies be destroyed—and throws in four months of jail time for its director. Bernardo Bertolucci escaped with a suspended sentence and an Oscar® nomination for his troubles. Aside from opening the floodgates for eroticism in mainstream cinema, this 1972 masterpiece also provides the stage for a powerhouse performance from Marlon Brando as a grieving widower seeking solace in a stormy anonymous affair. Don’t let the title fool you—the film is not about the “tango,” per se, so don’t go recommending it to your grandmother just because she’s a rabid fan of Dancing with the Stars. Fun fact: Brando was up against Al Pacino, Jack Nicholson and Robert Redford for the Best Actor Oscar® that year; they all lost to Jack Lemmon.
