Oscar winning actress Cate Blanchett has said that she never expected to appear in The Hobbit trilogy.

The Aviator actress reprises her Lord of the Rings character Galadriel in The Hobbit: An Unexpected Journey, despite her initial worries over the role.

In an interview with Flicks and Bits, Blanchett said: "I had no expectation that there would be anything more after the Lord of the Rings trilogy.

"I thought that was sort of the end of the journey - and my time on that trilogy was all too brief.

"I was there for three or four weeks, even though they shot for such a long time, I was only there for that amount of time."

Speaking about the casting of her role in The Hobbit she added: "I kept getting the answer that Peter doesn't know yet, because of course Galadriel doesn't appear much in The Hobbit book, so I was hoping against hope.

"And then when I got word that, in fact, she was going to be in a small section of it I was over the moon.

"It was a little bit like returning to summer camp, in that so many of the people that were a part of the first journey are a part of this journey.

"It's an amazing thing to be able to return to something that began 12 years ago."

The Hobbit: An Unexpected Journey opens tomorrow, Thursday December 13.
