Even if you haven't seen Frozen, there is no way you can't have heard about it.

The Disney animation was released at the end of 2013, but its impact has lasted through the whole of this year and plans for spinoffs, musicals, and sequels are already underway to cash in on the cultural phenomenon.

Frozen has grossed over $1 billion and is the highest-grossing animated movie of all time, winning the Best Animated Feature accolade at the Oscars.

A new Channel 4 documentary - Frozen at Christmas - will explore how this movie moved beyond being "just another" Disney princess tale and captured the imaginations of millions.

The film will also explore fan obsessions with the movie and the effect that it has had on their lives.

Channel 4's press release about the documentary reads:

"This one-off special for Channel 4 tells the whole story behind the film and its fans, celebrating its highlights and examining all aspects of the Frozen phenomenon. It hears from filmmakers, performers, celebrities, critics and, most of all, from UK fans who have made Frozen such a success. It also looks forward to the future of Frozen and what new Frozen events 2015 might bring."

Frozen is being adapted into a Broadway musical. It has spawned its own 'Frozen On Ice' skating show tour, and the success of singalong screenings has prompted the re-release of the movie on DVD and Blu-ray in singalong form.

The movie's producers have said that it is "too early" to discuss a full sequel, but short film Frozen Fever will be released in 2015 featuring the movie's characters Anna, Elsa and Kristof.

Frozen at Christmas is part of Channel 4's seasonal programming, which was announced earlier today (November 26).
