Now that he is spearheading advertising campaigns for Hitachi air conditioners, the Hong Kong Tourist Association and American Express credit cards it seems that Jackie Chan is the SAR's 'sell it all superstar'. Hong Kong's best-known face inside and beyond his home town, has become a 'cert' for companies looking for someone to shift their product in these troubled economic times. And judging by his plea to Chief Executive Tung Chee-hwa at the Hong Kong movie awards to crack down on pirate videos and laser discs, Jackie isn't beyond pitching his pet causes, as well as trying to sell commercial products. In his American Express commercial, Jackie is chased by a trio of cinematic villains through a variety of retailers and restaurants. 'The idea is to let consumers know that American Express cards can be used for purposes other than travel,' according to American Express senior vice-president and area general manager for East Asia, Ian Marsh. The Ogilvy & Mather-designed campaign will run only in Hong Kong for the moment, although Mr Marsh added there was a 'strong possibility' it could be extended to Singapore. More news of Manny Ayala, the Discovery Channel Asia staff member highlighted in this column last month. Yesterday, Discovery Channel general manager Kevin-john McIntyre announced in Singapore that Mr Ayala has been promoted to vice-president of programming operations and promotions. The move upwards will give Mr Ayala responsibility for all aspects of programming, including co-ordinating the use of staff and production facilities, regional programme-making and on-air promotions. What is not clear is how the promotion will affect one of Mr Ayala's apparent duties when he was merely Discovery's vice-president for programming. Readers will recall a photograph we ran last month illustrating the shooting of Living Asia - the first series commissioned by Discovery in the Asia-Pacific region. The still showed presenter Lea Salonga intently studying her lines, while behind her strode Mr Ayala clad in shorts and polo shirt - apparently carrying her baggage.
