Sir Ian McKellen has been passing time on The Hobbit set by coming up with a musical version of the tale, his co-star has revealed.
Flight Of The Conchords funnyman Bret McKenzie, who plays Lindir the elf in the upcoming fantasy film, joked that he, Sir Ian and Hugo Weaving had been plotting an alternative telling of the JRR Tolkien story.
"One of the highlights for me was working with Gandolf and Elrond, Ian McKellen and Hugo Weaving. We had a bit of downtime on set, so we started workshopping The Hobbit: The Musical. We came up with some pretty good stuff," he told The Hollywood Reporter.
Bret, who has finished filming his part, added: "It's amazing, (director) Peter Jackson is just rolling, he's really got his flow on.
"It's like the same magical Lord Of The Rings middle earth world, I've never seen anything so massive."
Bret also said his cult TV comedy Flight Of The Conchords could be made into a big screen version.
"We're going to try and do a movie, we just need a story so if anybody's got any good story ideas..." he said.
"Movies take a long time to make."
