GOOD MORNING: Dennis Hopper, who appeared with his friend James Dean in “Rebel Without A Cause” and “Giant” in 1955 and 1956, meets this week with Leonardo DiCaprio to discuss directing him in “James Dean” for producer Marvin Worth at WB. Hopper told me he wasn’t yet certain about directing the movie about his pal –”It better be great,” he laughed. Hopper starts his fifth decade in movies next year — he began with “I Died a Thousand Times,” a 1955 remake of “High Sierra.” Hopper went on to directing pix including “Easy Rider” and “Colors” and an Oscar acting nomination for “Hoosiers.” This year Hopper’s “Speed” heavy has won him critical praise and even some Oscar nom talk. He returned from four months in Hawaii on “Waterworld” to shoot interiors starting today, continuing to February. This heavy, he says, makes all others seem like “powder puffs.” And, over the weekend he filmed his fifth comedy commercial for Nike. It will be aired during the Super Bowl. He also films a commercial for Home Box Office to air during Super Bowl. In the latter, he appears as himself. Since his head is shaved for his super-heavy role in “Waterworld,” Hopper wears a funny hat for the Nike blurbs and wig wizard Ziggy Geike topped Hopper for Home Box Office. The commercials pay more than his million-$ feature fee!MICHAEL EISNER, RECUPED from his heart surgery, took his family (wife Jane and their three sons) to Orlando over the weekend to join celebs at the gala opening of Planet Hollywood in Disney World and Eisner lingers this week to ogle other new attractions in the park: “Honey I Shrunk the Audience,” as well as “Innoventions” at Epcot Center, where major U.S. companies contribute their latest inventions and gadgets soon as they come out of the labs. Eisner heads to EuroDisney in the spring when a major Space Mountain attraction bows for the Europeans. “It is the most aggressive attraction yet,” the enthusiastic Eisner asserts. “At the end, you’re shot out of a cannon!” He emphasizes of EuroDisney, “The European economic crisis is over. Our demise was exaggerated. And word of mouth will make it successful — as it has at all the parks”… Robert Ellis Miller, who first directed at WB in 1966 with Jane Fonda and Jason Robards in “Any Wednesday,” is reining the two-hour CBS “John Boy’s Wedding; A Walton Reunion” in the church on the WB backlot.

Cowan agreed — he never heard further … Dan Gordon, scripter on “Murder in the First,” will see his novel version out next month — it’s the first of a two-book deal with St. Martin’s Press.
