Meryl Streep and Steven Spielberg have rehearsed their red carpet appeal at yesterday’s screening of the HBO documentary “Spielberg”, about – you’ve guessed it, the visionary director’s career. Streep and Spielberg will share many more photo calls in December when their film “The Post” is being promoted. Additional coverage from Showbiz411: It was just your basic night at Alice Tully Hall for HBO and the premiere of Susan Lacy’s stunning “Spielberg” documentary. HBO welcomed a select crowd across the street for dinner at Lincoln Restaurant, where Spielberg and wife Kate Capshaw had the whole family– lots of kids, and lots of friends: Blythe Danner, her son Jake Paltrow, his wife photographer Taryn Simon, plus Meryl Streep, Tony Bennett, Mike Myers, Barry Levinson, Paul Haggis, Greta Gerwig, Danny Strong, plus HBO’s Richard Plepler, as well as actor Bob Balaban and writer wife Lynn Grossman, Gina Gershon, Marlo Thomas and Phil Donahue, Bennett Miller, and Spielberg’s legendary publicist since “Close Encounters,” Marvin Levy, the dean of Hollywood flacks. “Spielberg” begins airing on HBO tomorrow night. You’ve never had such a good reason stay home on a Saturday night.
