The Disney Animation chief creative officer has been blown away by the development of Frozen 3. With Princesses Elsa and Anna separated all throughout their childhood, thanks to Elsa's unstable ice powers, 2010's Frozen saw the sisters finally come together as a family. The movie was a massive success for Disney, totaling $1.285 billion on a $150 million budget and winning two Academy Awards. Since then, Disney Animation produced Frozen 2, which was even more successful at $1.453 billion on the same budget. Multiple shorts and TV shows have also been developed.
