On February 21st "Moana," Walt Disney Animation Studios' wind-swept adventure, splashes down on Digital HD and Disney Movies Anywhere (it's out on Blu-ray on March 7th). And to celebrate this release, we've got an exclusive look at some of the features; this one takes you behind-the-scenes for a look at the film's unique songwriting process.

In the clip, you get to see Mark Mancina, a composer who has worked on such animated Disney classics as "Tarzan" and "The Lion King;" Lin-Manuel Miranda, the Pulitzer Prize-winning playright behind "Hamilton" (and an Oscar-nominee this year for another "Moana" tune, "How Far I'll Go"); and South Pacific songwriter Opetai Foa'I, collaborate on "We Know the Way." If you know and love "Moana" (and if you've seen it already, you love it), you know how important this song is, both in terms of setting up the movie's central theme of finding your own calling and forming the narrative bedrock for Moana's journey out to sea. And the song is just so good too.

So seeing how it was formed, with three musicians from wildly different disciplines, is both inspiring and educational. Who else is ready to go on an adventure?"Moana" is on Digital HD and Disney Movies Anywhere on February 21st and on Blu-ray on March 7th.
