What film features the song "Happy" by Pharrell Williams?

The film that features Pharrell Williams’s song “Happy” is Despicable Me 2.

Released in 2013, “Happy” was written, produced, and performed by Pharrell Williams for the film’s soundtrack. It appears during the animated sequel’s upbeat musical moments and was created as one of several original songs Williams contributed to the project. The soundtrack also includes “Just a Cloud Away” and “Scream,” featuring CeeLo Green.

The song became much bigger than a typical movie soundtrack track. It was released as a single later in 2013 and helped promote the film through an unusual 24-hour interactive music video featuring dancers across Los Angeles. “Happy” topped charts in more than 19 countries, became one of 2014’s biggest global hits, and received an Academy Award nomination for Best Original Song.

A common mix-up is associating “Happy” with Pharrell’s album Girl, released in 2014. Although the song was included on that album, its original film connection is Despicable Me 2. It is also sometimes confused with songs from the first Despicable Me, whose soundtrack features different Pharrell contributions.
