GOOD MORNING: Sleeping Beauty’s Castle at Disneyland will undergo a golden transformation between the hours of 10 p.m. Wednesday and 10 a.m. Thursday. That’s when Julie Andrews, worldwide ambassador for the Walt Disney Parks and Resorts, will push a button launching the 50th anniversary global celebration of Disneyland. Bob Iger makes the opening remarks followed by Art Linkletter, who was on hand for the opening 50 years ago. Following will be live feeds from the parks in Japan, Hong Kong and Paris (with Gerard Depardieu) and Wayne Brady from Disneyworld in Florida and Kermit the Frog from the Disney cruise ship. Next, Michael Eisner welcomes and intros Andrews. I spoke with Julie about her relationship with Walt which dated back to her stand in “Camelot” on B’way in 1961. He came backstage and offered her the role in “Mary Poppins.” “But I’m pregnant,” she said. “We’ll wait,” Walt told her. And the rest is history. She says, “Who knew this visionary man with pixie dust in his pocket and a sparkle in his eye would change the life of this then 27-year-old forever more.” But she didn’t work for Disney again for 40 years — in “The Princess Diaries.” Julie did an extra on-camera stint for Disney in the two-disc “Mary Poppins” DVD in which she filmed the P.L. Travers short, “The Cat That Looked at a King.” The success of this DVD has resulted in Julie doing a ditto double DVD , this one for Fox on “Sound of Music’s ” 40th anni with a scene to be shot with Christopher Plummer and children … Disneyland’s 50th anni edition DVD “Disneyland: Then, Now and Forever” includes 50 interviews hosted by Julie. Here are a few: Diane, Ron, Roy E. Disney, Eisner, Richard Cook and George Lucas.

WHEN I SPOKE to Max Schell Monday, (about directing “Der Rosenkavalier” for the L.A. Opera), I also asked about his sister Maria. He had been caring for her during her lengthy illness and told me, “I visit her every day — she lives but 50 meters from my house (in Austria).” We reminisced about his “achingly poignant” film portrait of her, “My Sister Maria” (2003), in which he showed the tragedy of her life’s medical history–as well as her artistic triumphs. She died Tuesday and Max wings home for Saturday’s funeral, returning Monday to go on with the opera which bows May 29. Wednesday, Max told me “She is irreplaceable. She was my idol.” He added, “actors don’t die–they are preserved in their films.” I had met Maria in her glory days in Hollywood and, like Gary Cooper and Marlon Brando were, I was bowled over by her soft beauty. … On Sunday, a memorial for writer-producer Paul Henning will be held 1 p.m. at the Writers Guild Theater. He died March 23 at age 93. His credits range from TV’s “The Beverly Hillbillies” and “Petticoat Junction” to bigscreeners “Lover Come Back” ( Doris Day and Rock Hudson) and “Bedtime Story (Marlon Brando and David Niven). Film clips will be shown plus reminiscences by Art Linkletter and Paul’s daughter, actress Linda Kaye Henning.
