It may sound like an “SNL” sketch, but “Citizen Kane” legend Orson Welles pitched HBO on a miniseries in the 1980s. The unlikely meeting is documented in “My Lunches With Orson,” a collection of transcripts of recordings the Hollywood immortal asked director Henry Jaglom to make of their regular chats together. In a Harper’s magazine excerpt before the Peter Biskind-edited book comes out in July, Welles explains to an unnamed HBO executive his series idea is set at a resort — “where the richest people in the world go . . . in a Central American country . . . overthrown by a coup d’état.” When the honcho replies, “I’m very interested in doing something about the Dominican Republic,” Welles counters, “I wouldn’t be remotely interested . . . I’m not interested in real history, because I know Latin American politics to an unbelievable degree. I’m an expert on it . . . we’re not getting anywhere.” When the meeting spirals further out of control, Jaglom interjects, “No, no. Wait, wait, wait — wait! We’re just trying to understand,” but Welles snaps, “I’m not gonna go on,” and says of the cable suit, “She doesn’t like rich people!” The flustered HBO exec pleads, “It does interest me very much,” and Welles shoots back, “I can’t do it . . . I have to get a little spark from somebody. If I don’t get it, that’s it.” The exec finally says, “You’re not listening because you’re so angry” and storms off. Welles coolly quips to Jaglom, “I don’t need to be iced off like that.”
