What am I doing here?: Orlando Bloom recalls what he thought after joining 'The Lord of the Rings'

"For me, as a young actor, I remember sitting there coming out of drama school with all of these legends," said Bloom during a 'Lord of the Rings' panel at Awesome Con in Washington, D.C., adding, "And thinking, 'What am I doing here? How did this happen? This is unbelievable'," reported People.

"It was a feeling of excitement," he added while talking about filming the first of the movies, which was released in 2001.

"I mean, I was 20. We'd read the books and had a sort of understanding of what this could possibly be, but not really knowing anything because it was my first movie experience. I was just like an open vessel, and it's about that sort of anticipation, that excitement, that sort of sense of possibility, that feeling that your whole life is beginning and you're beginning this remarkable journey. If I could bottle that feeling and give it to you all... I think we also never could've known -- I don't think any of us really knew what we were stepping into."

Bloom, who played elf Legolas in the films, was joined by costars Liv Tyler, Sean Astin and Jonathan Rhys-Davies at the panel.

Tyler shared that "the whole experience was so exciting and terrifying just to be a part of the whole world, the vastness of the material. I felt so much responsibility and I still do. I get nervous when I talk about it. There was just so much that we had to learn," as per the outlet.

Talking about her character, Arwen, she said, "is a beautiful character who's a little bit mysterious because there's not as much of her in the books. So we were sort of figuring out how to communicate into the films and create her story, which took a few turns over the years. I guess I'm still sort of in awe and inspired by her today," she said. "We were so young. It was hard to fully understand everything as it was happening," reported People.

'The Lord of the Rings' trilogy ultimately grossed a historic 2.9 billion dollars worldwide.
