Frozen became a huge hit in 2013, and shoved "Let It Go" into the pop culture consciousness (not to mention the ears of many resentful parents). Which means the expectations for Frozen II are higher than the north mountain. Check back in with Elsa (Idina Menzel), Anna (Kristen Bell), Kristoff (Jonathan Groff), Olaf (Josh Gad) and Sven (himself) with the new trailer.
Chris Buck and Jennifer Lee (who since the first film has become the chief at Walt Disney Feature Animation) are back to direct a story that draws from the sisters' past and weaves in yet more magic. Elsa's powers, always a mystery, come into play again, but rather than worrying that they're too much, she's now concerned that they might not be enough for the challenge that lies ahead. Haunted by a sing-song siren call that beckons her towards an enchanted forest, the scene is set for an adventure that'll test every one of the group.
Sterling K. Brown, Jason Ritter, Evan Rachel Wood and Alfred Molina are amongst the new voices here, with Frozen II sweeping onto UK screens on 22 November.
