A documentary on the phenomenal success of Disney’s animation film Frozen has been made by a new business venture of independent television production firm Rondo Media.

Rondo’s new subsidiary business Yeti was commissioned by Channel 4 to make Frozen at Christmas, which will be broadcast on Christmas Day at 8pm.

Narrated by Dawn French it features a host of familiar faces and highlights and examines aspects of the most successful animated film of all time.

Working with the co-operation of Disney, the Cardiff based company travelled to Los Angeles to meet the film’s creators and also spoke to fans closer to home in Wales.

It will include a special sequence featuring Frozen sing-a-long filmed at St David’s Hall in Cardiff which includes a performance by the choir of Howell’s School in Llandaff.

The programme’s producer, Tom Ware, from Yeti said: “The whole story of Frozen and the film’s unparalleled impact on audiences across the globe, young and old, is fascinating.

“It’s broken new ground in so many ways – from the strong but complex female role-models to the use of social media to share fans’ musical tributes. It’s been a joy to make and we’re extremely proud that a Wales-made television programme is to be shown to a potentially huge UK audience in a prime time Christmas Day slot,”

The programme will be repeated on New Year’s Day.

Yeti’s commission had a value of just over £200,000.
