The original cast was blown away by their impromptu performance with a call for a petition for the stars to do a live-action remake of Frozen.
The duo acted out the Frozen scene in between filming scenes for Stranger Things 3.
Millie played Elsa while Sadie played sister Anna.
They performed the scene where the sisters finally reconcile to save Arendelle.
Let’s hope they do this in real life! -/TISG
