Learning to embrace the moment and relax a little bit is a timeless throughline in literature, but this theme is deployed with particular success in Zorba the Greek, the 1964 film based on novelist Nikos Kazantzakis’ book The Saint’s Life of Alexis Zorba. The story follows the simple friendship between Basil, an awkward author who visits Crete to check on one of his father’s mines, and Zorba, the larger-than-life native who assists Basil and teaches him to dance. The film has entertained generations of audiences and raked in millions at the box office. This weekend, it screens at the National Gallery of Art as part of a tribute to Anthony Quinn, the joyful actor who played Zorba. His widow will introduce the screening and comment on her connection to the film, as well as Greeks’ love for her late husband. The film shows at 4 p.m. at the National Gallery of Art, 6th St. and Constitution Ave. NW. Free. (202) 737-4215. nga.gov.
