JULY 21 & 23

It was Harriet Andersson’s skinny-dipping scene that attracted Woody Allen to this, the first Ingmar Bergman film he ever saw, but these days that no longer seems the 1953 film’s most interesting aspect. Bergman is known for his stylized adult dramas, but this is the naturalistic tale of two teen-age lovers—bold, working-class Monika (Andersson) and suggestible, middle-class Harry (Lars Ekborg)—who abandon their crummy jobs and depressing homes, commandeer a boat, and spend an almost-idyllic summer among the islands near Stockholm. With autumn comes a bitter epilogue: Monika is pregnant, so the two marry, but Monika finds grown-up responsibilities a lot less agreeable than the summer that preceded them. “I have never made a less complicated film,” wrote Bergman, but the final scenes powerfully complicate the sunny basic scenario. Friday at 6 p.m. and Sunday at 7 p.m. at the Kennedy Center’s American Film Institute Theater. $6.50. (202) 785-4601. (Mark Jenkins)
