Disney chairman Alan Horn has declared that the entertainment giant has not even discussed the prospect of a follow-up to Frozen yet.

The movie has become the highest-grossing animated film of all time since its release last year - with toys and merchandise selling out globally.

But the big cheese told a crowd at the Tribeca Film Festival in NYC that the corporation is focused on turning it into a Broadway show before it churns out a movie sequel.

The chat also saw Horn quizzed about Star Wars Episode VII casting decisions - and particularly whether Girls star Adam Driver is set to play a villain.

He was determined to stay tight-lipped however, saying: "You know I really can't. I want to save that for the Star Wars filmmakers, it should be their announcement."
