    Pharrell's 24-Hour Interactive Music Video Stars Lots Of Celebrities

    The video for "Happy," includes 24 scenes with Pharrell and appearances by Odd Future, Steve Carell, Magic Johnson, and the streets of L.A.

    It must be the week of the interactive music video. First, Bob Dylan releases the music-video-posed-as-a-TV-screen for "Like a Rolling Stone."

    Then, Pharrell releases this 24-hour-long video — from midnight to midnight — looping his song "Happy" with a different dance scene for each time it's played. The song is from the Despicable Me 2 soundtrack.

    The video includes appearances by Steve Carell, Odd Future, Jamie Foxx, Kelly Osbourne, Magic Johnson, and others. Pharrell appears at the top of every hour. Many of the scenes are filmed around Los Angeles in front of gawking passers-by.

    It's fun enough to flip through yourself when you have a few minutes (or hours) — but here's your guide to some of the video's highlights.
