Think you're a Frozen snow-it-all? You will be after reading these cool facts!

1. Frozen is the highest grossing animated feature film in history, knocking Toy Story 3 off the top spot. Sorry Buzz and Woody!

2. Elsa, aged 21, is the oldest of the Disney Princess bunch (although she’s technically a queen). All the rest are teenagers.

3. She’s also the hairiest! Disney animators developed a new program to assist in creating Elsa’s perfect plait. Her head has 420,000 CGI strands whereas Rapunzel from Tangled, famed for her long locks, had a mere 27,000.

6. The names of some of Frozen’s characters are said to pay tribute to the author Hans Christian Andersen, who wrote the story The Snow Queen, on which the film is based. Sound it out: Hans, Kristoff, Anna, Sven. Clever!

7. Olaf’s dance with the seagulls during In Summer is a nod to Bert’s penguin dance in Mary Poppins. Oh it’s a jolly holiday with Olaf…

8. The end credits contain a list of 34 babies who had been born to crew members during the lengthy production of Frozen.

9. It also contains a disclaimer stating that Disney does not endorse Kristoff’s views that all men eat their own boogers… good to know.

10.  All Disney feature films contain a hidden Mickey Mouse. In Frozen, it’s on the shelf in Wandering Oaken’s Trading Post and Sauna. You have to look really, really closely, but he’s there!

11. On the topic of Oaken, he may be one of Disney animation’s first openly gay characters. When introducing his family in the sauna, we are shown a man with kids, suggesting that Oaken has a same-sex partner. Yoo hoo, hi family!
