Frozen 2 SPOILER: Kristoff star Jonathan Groff lets slip Anna bombshell 'Spoiler alert'

When the crowd let out a few gasps, he caught himself, adding: “That’s kind of a spoiler alert I guess!

“And it’s not going well for him because he’s a mountain man and he has trouble expressing his feelings, particularly, as far as love is concerned,” Groff continued.

“About half way through the movie it’s another failed attempt at a proposal and a fantasy sequence happens where Kristoff lets loose singing an ‘80s-inspired emotional ballad.”

Explaining what the Lost In The Woods looks like visually, he added: “The animation is sort of like an ‘80s music video.”
