There must be something behind the wave of nostalgia, the return to the fine, classic films that are being screened this summer.

In Rouben Mamoulian’s “Queen Christina,” Greta Garbo showed her mettle as a great star and successfully demanded to play opposite John Gilbert rather than the young Laurence Olivier, giving him an opportunity to act in the talkies.

Michelangelo Antonioni’s 1962 movie “L’Eclisse,” with Monica Vitti and Alain Delon as a couple who fall madly in love in 1960s Rome and get caught up in the toils of loneliness, is the third in his trilogy, after “L’Avventura” in 1960 and “La Notte” in 1961. He followed that with “Blowup” in 1966.
