“Happy” was originally conceived for the soundtrack of the animated film Despicable Me 2 . Director Pierre Coffin wanted a song that captured the unbridled joy of the Minions celebrating Gru’s birthday. However, when Pharrell delivered the demo, the team realized they had something far bigger than a kids’ movie track.
