Disney's newest animated delight, "Frozen," doesn't open for a few more weeks, but already anticipation is building, like layer after layer of frost.

Back at the D23 Expo over the summer (a kind of Disney-only Comic Con), people were already dressed as the characters from the movie -- the fair princess Anna (Kristen Bell) and her witchy sister Elsa (Idina Menzel), better known as The Snow Queen. Now that's the power of prerelease hype.

But so far the trailers for "Frozen" have been somewhat lackluster, failing to capture that "classic Disney" spirit that the movie really embodies (I've seen it and it is spectacular). Well, that has just changed with an online-only trailer that wonderfully exhibits the tone and spirit of the movie. In fact, this trailer gives off the vibe that "Frozen" that could have followed, say, "Beauty & the Beast" in the Disney lineage. Because it really could have; it's that good.

Based loosely on Hans Christian Andersen's fairy tale "The Snow Queen," a story that Walt Disney himself tried unsuccessfully to develop in the studio's post-war years, "Frozen" follows Anna's quest to thaw Elsa's heart and return the kingdom to less icy conditions. Kristoff (Jonathan Groff), a gruff mountain man and Olaf (Josh Gad), a chatty snowman, join Anna on her quest. It's a magical movie, folks. The trailer calls it "The Greatest Animated Event Since 'The Lion King,'" which is pretty fair. It also doesn't hide the fact that the movie is (gasp) a musical, with some really, really wonderful songs.

If you aren't jazzed about "Frozen" already, well, this trailer will probably make you want to start in on your own Elsa and Anna costumes for the next D23 Expo.
