Martin Freeman has admitted feeling "daunted" as he prepares to step into Bilbo Baggins' shoes for The Hobbit.
The Sherlock star is due to start filming the Lord Of The Rings two-part prequel alongside director Peter Jackson and actors Sir Ian McKellan, Andy Serkis and Cate Blanchett and revealed he is nervous about heading to New Zealand.
"It's very daunting - the daunting part is leaving home... I'm a real homebody, even before we had children, I was a homebody, so with children it's like aww... I'm very excited though," he told Modcast host Eddie Piller.
Martin initially turned down the role because of his commitments to the BBC detective drama.
"I had to turn it down because of being contractually obliged to do the second series of Sherlock for the BBC, which we are doing in the middle of this year," he recalled.
"I turned it down with a very heavy heart because things like this don't come your way very often. It's a once-in-a-lifetime opportunity, as far as scale is concerned. It's a huge, huge deal. But I was contracted to do Sherlock. I wanted to do both."
The dad-of-two added: "When I found out I couldn't do both it was very sad. And then it was very flattering when Peter Jackson rearranged the filming around my availability."
Part one of The Hobbit is expected to be released in 2012, with the second part following in 2013.
