International film star Jackie Chan was at his playful and patriotic best on Saturday in Beijing, as he helped launch China's official Olympic song "Best Wishes From Beijing." It's a follow up to "Beijing Welcomes You", the theme song for the 2008 summer Olympic games.

"Best Wishes From Beijing" features more than 100 singers and movie stars from Hong Kong, Taiwan and the mainland, including actress Zhang Ziyi, Gong Li and pianist Lang Lang.

Stars appear at iconic landmarks around Beijing in the music video, from old hutong alleyways to the grand and ancient Forbidden City.

Jackie Chan said celebs were desperate to get their chance to play a part in the song.
