Jacqueline Kennedy began socializing with artist Andy Warhol after her husband’s assassination in 1963. Warhol had made portraits of her following JFK’s death; eventually, the pair became chummy, and Warhol welcomed the widowed first lady and her family for weekend stays at his home in the Hamptons. There, Kennedy welcomed filmmaker Jonas Mekas to teach her children and their cousins the basics of filmmaking. Mekas later turned the footage into a short documentary, This Side of Paradise, which screens this weekend at the National Gallery of Art. The shots are simple and feature JFK Jr. and Caroline engaging in basic activities like flipping through books and playing with the dogs, further humanizing the family Americans spent decades obsessing about. The film shows at 4 p.m. at the National Gallery of Art West Building Auditorium, 6th Street and Constitution Avenue NW. Free. (202) 737-4215. nga.gov.
