In a breach of massive Chinese security, a Korean television cameraman walked into Beijing's National Stadium, filmed some of the rehearsals for the Olympic's Opening Night ceremonies, returned, and saw his efforts go viral -- appearing not only on YouTube, but also on mainstream network programs in the U.S. The video showed a procession of athletes wearing white suits, posing as Olympic athletes and greeting the crowd, and an assemblage of kung-fu performers battling it out in the stadium. The London Daily Telegraph described the film this way "In perhaps the most impressive footage, serried ranks of performers dressed in huge boxes rise and fall in what appears to be a visualization of the continuous building of skyscraper blocks that is China's current cultural master-achievement." The opening ceremonies performances are being directed by Chinese film director Zhang Yimou.
