From a 1977 NYT piece about the film:

“Cuba: The Castro Generation” was produced, directed and written by Arthur Holch. The on‐location film footage is not dramatically different from most of the scenes recorded by other American visitors in recent years, but the content takes on additional interest in the light of President Carter's conditional statements about being willing “to move toward normalizing relationships with Cuba.”

Unlike CBS News and Bill Moyers, ABC was not able to get a private interview with Cuba's “maximum leader.” As Howard K. Smith explains: “Everything we asked to see, we were allowed to ... with the exceptions of militia and political prisons, and a talk with Fidel Castro.” He adds: “And everyplace we went, we were accompanied by guides from the Foreign Ministry.” But ABC does a commendable job of getting beneath superficial images, down to the observation by a Cuban shopper that the presence of the film crews may have had something to do with the unusually lavish display of meats in a supermarket.

In addition, Mr. Smith, his relatively conservative attitudes in firm tow, becomes an unusually persuasive spokesman for “normalizing” relations. Noting that Cuba has survived largely through Castro charisma and Soviet rubles, he also stresses that Cuba's hostility toward the United States “is bascd on our exploitation of Cuba before Castro and attempts to invade Cuba or assassinate Castro since.” Whether you like Castro, or dislike him, the documentary concludes, a ieturn to normal relations is “the only reasonable recourse.” The documentation and treatment are solid. The executive producer of the Closeup series is Marlene Sanders.
