'Sound of Music' cast reunites on Oprah

Oprah was alive with "The Sound of Music" Thursday, as all nine stars of the movie musical reunited for the first time since the Academy Award-winning best picture was released in 1965.

"It made my career," said Julie Andrews, 75, on "The Oprah Winfrey Show." "It was that big a movie, and we had no idea, really, at the beginning that it was going to be that huge."

She had questioned taking the role as governess to an Austrian widower's large brood of children after having just played a magical nanny in the hit "Mary Poppins." "But it was such a delicious role, and the music is so beautiful," she told Winfrey.

Co-star Christopher Plummer, 80, who has avoided such reunions in the past, also admitted he'd had trepidations before taking the role of patriarch Captain von Trapp.

"I wanted to do a musical, and that was what attracted it to me," he says. But the part of patriarch Captain von Trapp "as written was not exactly 'Hamlet.' " Together with screenwriter Ernie Lehman, he got "some meat off the bones" and that "it turned out to be quite all right."

Charmian Carr, who was 21 when she played 16-going-on-17 Liesl von Trapp, was staying at the same hotel as Plummer, and admitted to having had a crush on him.

"He was so perfect, and he spoke with this perfect British accent."

The show also featured performances of "Edelweiss" and other songs from the movie by some of the real von Trapp great-grandchildren, who sing at festivals and in concerts around the world.

The cast was promoting the release of movie's 45th-anniversary DVD and Blu-ray next week.
