A towering underwear advertisement on the defunct Ritz-Carlton Hotel building in Central has attracted not only attention but also complaints. The ad features African-born actor Djimon Hounsou, of Blood Diamond fame, wearing nothing but a pair of white briefs by Calvin Klein. Three people voiced their displeasure to the Television and Entertainment Licensing Authority, saying the image was indecent. Tela said it had conducted an investigation and concluded that the ad was neither indecent nor obscene as it did not violate the Control of Obscene and Indecent Articles Ordinance - the star's sensitive parts were hidden carefully by the briefs. Calvin Klein Asia said no complaints had been received. The outdoor ad, which covers the height of the hotel, is the largest of its kind among Calvin Klein commercials in the region. It is the only ad displayed on the hotel after it closed down. Post reader Philip Richards said the ad constituted visual pollution as 'this site overlooks one of the rare open public parks in Central, and borders the historic Legco building and the Cenotaph, and faces Hong Kong Park'. Chinese University journalism professor Annisa Lee Lai Chun-hing said the government should regulate outdoor advertisements. She said television content deemed unsuitable for children could not be shown during the family viewing hours of 4pm to 8.30pm, but for outdoor ads 'we have no choice but to see them. We are not looking at the ad in a protected environment, and there is no time limit set for outdoor ads'. The ad will be displayed until April 15 before the hotel is pulled down.
