According to the main actor in this commercial, Jayson Li:
"The campaign I worked on for NutriGreen's LDF Cordyceps Health Supplement (《綠養坊》LDF純冬蟲夏草) was launched not too long ago. The "Rocketeer" campaign consists of a television commercial, directed by Chan Man Chung, and a print ad with the production house being Film Factory and the advertising agency being Leo Burnett Hong Kong. The TVC was recently featured in the Chinese language newspaper Ming Pao (明報), Attuworld Nederland and on Virgin Radio Toronto. The TVC was also recently screened at the Cannes Lions 58th International Festival of Creativity which was held at the Palais de Festivals in Cannes, France."
Note: This commercial was also selected as a winner in the 2011 Spikes Asia - Asia's Creative Advertising Festival and Awards.
Brief Explanation:
"Most people in Hong Kong live a crazily hectic life - long working hours, overtime on weekends, and a packed social life. Most of them feel drained before they even get up in the morning. To dramatize this phenomenon, this commercial shows how a businessman loses his energy before he even gets to work. The answer of course, is Nutrigreen LDF Cordyceps, a health supplement that helps people maintain their energy level throughout the day".
