One is a global blockbuster movie trilogy, the other a homegrown TV show but it's Sherlock rather than The Hobbit that has had the biggest impact on the life of star Martin Freeman, thanks to the detective drama's fervent fans.
“It's probably Sherlock," says Freeman, when asked which of the two franchises has had the greatest effect on him. "The Hobbit was an extremely big gig. It’s enormous. But when people make themselves known to me it is more for Sherlock.”
The actor who plays Dr John Watson in Sherlock and the eponymous Bilbo Baggins in The Hobbit films is promoting the second instalment in the movie trilogy on The Graham Norton Show tonight and says he has now completed all three after a mammoth two-and-a-half-year project.
“It’s done, it’s all finished – for however long your think you are going to be in a Peter Jackson film, you are going to be in it longer. It was a long gig," says Freeman. "My main challenge was checking in with Peter to see where Bilbo was at a given time. Two and a half years is a very long time to keep a handle on it.”
One thing the star did take time out to do, of course, was film the third series of Sherlock with Hobbit co-star Benedict Cumberbatch. The detective drama returns to BBC1 on New Year's Day after an absence of two years and will finally explain to those avid fans how Sherlock survived his fall from the roof of St Bart's Hospital.
The Graham Norton Show is on Friday 13 December at 10:35pm on BBC1
