Marilyn Beck is sort of a low-budget Louella (or if you've forgotten her -- sort of like Rona Barrett) presumably talking about the ""New Hollywood, the Now Hollywood"" or inevitably ""The Turned-on Hollywood"" and the decline of the big studios and the big stars and you might even wonder about that of the New York Times since she's a syndicated columnist for their ""Special Features."" Anyway here are all those ""eager darlings"" -- Dennis Hopper and Peter Fonda (""We've taken over"") and Janis and Jimi. . . the rise of drugs and the show of skin and violence. . . but then you'll know some of the others -- Julie Andrews ""sheer perfection, absolute magic"" or Deborah Kerr benignly approving of the new folkways. Although you'll be pretty surprised to find J.C. (that's Johnny Carson) converting ""an empty champagne bucket into a urinal"" at a public banquet. Dreadful stuff, really -- and there's a justified nostalgia for the Brown Derby and the Garden of Allah and all those other footprints in the sands of cement at Grauman's Chinese.
