"Heart," United's new brand ad, portrays the connection between a husband and wife and United's role in reuniting them. The commercial depicts a woman leaving her husband to fly to Europe for a business presentation. As she says goodbye, she leaves her heart behind as a symbol of her love. The musical score for "Heart" is a piano duet of Rhapsody in Blue performed by Herbie Hancock and Lang Lang, who recently performed Rhapsody in Blue together at the 2007 Grammy Awards. Using stop-motion animation and paper puppetry, California-based director Jamie Caliri and his team, place dimensional cardboard puppets in miniature sets that were shot frame by frame.
