Author George R. R. Martin has revealed that he is pleased with the television adaptation of his series Game Of Thrones.
According to Entertainment Weekly, Martin described the HBO show as "spectacular" but admitted that he is worried about what fans of the books will think.
"My fear is there may be an element of fantasy fans that are like, 'It's not Lord Of The Rings'," he said. "We don't have Peter Jackson's budget... we can't do Battle of Pelennor Fields. We have to accept this is television... it's spectacular TV."
He added: "The Battle of Blackwater is a potential budget buster. They're going to have to figure out how to do that. It could be an entire episode of battle."
Martin also revealed that he is pleased with the length of the series, saying: "I think 10 hours has proved to be enough. You're always a little greedy - I wouldn't have minded 12 hours - but 10 worked too."
Game Of Thrones will premiere on HBO on April 17. It will air on Sky Atlantic in the UK.
