Frozen star Jonathan Groff has said he found the film's focus on familial love refreshing.
The actor, who voiced Kristoff in the film, is quoted by Digital Spy as saying of Frozen's incredible success, "It's so much about timing.
"And I think that the message is... Frozen is your traditional fairy-tale Disney film with all the great music, and characters like Olaf - but the story was about familial love as opposed to a woman looking for a man."
He added, "It was so refreshing - I think the concept was so refreshing - and the music was great, and so I think it was a combination of things. But it definitely took everybody by surprise."
