Here are seven things we learned from Disney's "Frozen 2" trailer, including what Anna and Elsa are really up to and who returns for the sequel.

In the trailer for 'Frozen 2,' Idina Menzel's Elsa and Kristen Bell's Anna leave their homeland of Arendelle.

Frozen 2 brings a lot of additional music to the hit Disney franchise, but there’s also a slate of new characters joining Elsa, Anna, Kristoff and Olaf on their journey!

There was no announcement that Anna and Elsa would be undergoing changes at Disneyland or Walt Disney World, the characters are also at Hong King Disneyland and Disneyland Paris in their new duds.

‘Frozen 2’ and Its Unanswered Elsa Questions 'Frozen II' skims the surface of a world and a character. It never really explores how Elsa got her powers.
