Trolling.

Film Being slightly too old to care at the time, I never did own a troll, the only kind I really encountering as a child being the monstrosity that menaced the three billy goats gruff in a Ladybird book. So the fact of a film based on The Trolls entirely passed me by until this morning when a friend sent me a link to a cover of Lionel Richie's Hello sung by Zooey Deschanel (Spotify).

Like The Lego Movie soundtrack, it's a franchise album which punches well above its weight in talent and material thanks to having Anna Kendrick and Justin Timberlake as Executive Producers.  Mostly covers of really cool songs, there is some original material including an "I Want" song from Kendrick (Spotify), which has a chorus which sounds like Price Tag and a Millennial Whoop.

Collider has an interview with Justin and Anna about the production process:

"TIMBERLAKE: So, my job for that was just hopefully to put our own spin on it, make it sound unique, and make it sound like it belonged in the scene, much like musical theater, almost. And then, I also wrote four original songs, specifically written for the movie. I’ve never done anything like that, either. Some of the music does sound very ‘70s. Overall, you’ll feel that a lot of the music definitely has a little bit of ‘70s funk to it, so that was definitely an inspiration for “Can’t Stop the Feeling,” as well. You get to see some of the animation and what they’re working on, so you get to see how big a moment is. When you finally get to see where the Bergens live, you hear The Gorillaz. You just want to sonically complement that."

Sadly this film itself looks like a fairly perfunctory quest narrative but you can't have everything.  [Thanks Talia!]
