Elijah Wood says strangers are still yelling "Frodo!" at him on the street.
The Hollywood star, 30, appeared in the last Lord Of The Rings film eight years ago, but is slipping back into his hairy feet for The Hobbit movies.
Asked if passers-by had stopped calling him by his character name, he tells The Graham Norton Show: "No, it doesn't go away, it's pretty perpetual."
And he says of the success of Lord Of The Rings: "It's strange - I don't think there is anywhere in the world that doesn't know the film."
He tells this Friday's BBC One show that despite constantly being called Frodo, he couldn't resist reprising the character, saying: "It was eight years ago that we finished the last film and in my opinion that was it.
"At the time there was no more to do with Frodo, but when I was asked if I wanted to come back I said, 'oh my God', it's a dream to revisit that time in my life."
Elijah returns in the Lord Of The Rings prequel with co-stars Cate Blanchett as queen Galadriel, Sir Ian McKellen as Gandalf and Andy Serkis as Gollum.
Martin Freeman stars as hobbit hero Bilbo Baggins in the 3D films, due for release in December 2012 and December 2013.
