Into the Unknown

"Into the Unknown" is one of the songs from the 2019 animated Disney film Frozen 2.

In January 2020, a representative from The Norristown Channel confirmed that Panic! at the Disco's version will serve as the theme song for Unknown Theory, a comic series that was created by Rebecca Leonard and co-produced by her sister June. The reason why the Leonard sisters chose Panic! at the Disco's version is because "It's 1,000,000,000 times better than Idina Menzel's version." The girls also said that the characters in Unknown Theory also prefer Panic! at the Disco's version.
