"Sunshine" for US Department of Health. Created by Saatchi & Saatchi, New York. Made by Gorgeous, London. Music by Solid State Revival.
Rant: For all the brilliant execution, the 'play outside' connect is a tad weak. The ad looks gorgeous. It would have won my vote if the blokes at Saatchi had pitched this idea to an energy company or a cell phone with night glow.
