The Lord of the Rings director revealed on Saturday (24Nov12) that he was rushing to put the finishing touches to the film ahead of the red carpet event - and he succeeded in his mission.
Elijah Wood, Cate Blanchett, Martin Freeman and Andy Serkis were among the stars of The Hobbit: An Unexpected Journey who took to the red carpet for the premiere, and Jackson admits he found the massive event overwhelming.
He told reporters, "It's emotional and very humbling to see all these people in my hometown who've turned out.
"It's been two years with this narrow focus on the film where we're trying to keep everybody out. You have security, you don't want people to know what you're doing.
"Then you get to that moment where filming's over and 100,000 people come along to the premiere, it's kind of like the whole world has turned upside down."
The movie, the first of three films based on the book by J. R. R. Tolkien, will hit screens in December (12), with the second part in the trilogy set for release next year (13) and the final installment scheduled for 2014.
