The year of Pharrell is coming to an end, but not without this pretty huge finish. “Happy,” a song from the Despicable Me 2 soundtrack, has been made into what’s billed as the world’s first 24-hour music video. It’s a huge, happy, dance-y, smile-y adventure of a thing with cameos from Jamie Fox, Steve Carrell, Tyler, the Creator, Earl Sweatshirt, Jimmy Kimmel, and Magic Johnson, but better yet it just features a lot of normal folks having a good time. Directed by the We Are From L.A. group, the camera only cuts during occasional moments to focus on the ground or sky, making edits really subtle (kind of like what Hitchcock did in Rope) and giving it this really seamless flow over the day it takes to watch. And if 24 hours isn’t enough, it also ends right where it starts, Finnegan’s Wake style, so you could technically watch the video in an endless loop. Watch a 4-hour clip below, but the curious should check out the video 24-hour song.
