Sia Furler covered the song for the soundtrack for the 2014 film. The single charted in Australia, Belgium, UK and in Poland where it became an airplay hit—the song peaked at number 3 on the Polish Airplay Top 20 Chart and at number 2 on the Polish TV Airplay Chart. The video for this song was filmed in New York City and it shows cast members from the 2014 film as they spread cheer to the citizens of New York City by dancing, performing random acts of kindness and holding signs with the word "smile" written on them.
