Arnold Worldwide has appointed Marc Sobier and Greg Farley as SVP, group creative directors, reporting to Global Chief Creative Officer Jim Elliott. Sobier and Farley, who both previously worked at Y&R New York as executive creative director and creative director respectively, are based in Arnold's New York office, but will supervise teams out of both Boston and New York. The pair worked with Elliott at Y&R NY, where they earned several Cannes Lions for their creative efforts on Land Rover USA. Their work on "The Vanishing Game," an interactive adventure story for Land Rover penned by author William Boyd, earned one of five ADC Tomorrow Awards for 2015. The three had previously also worked together at Goodby Silverstein & Partners.
