Here the trailer of The Forbidden Kingdom, the highly anticipated movie starring both Jackie Chan and Jet Li:
"A discovery made by a kung fu obsessed American teen sends him on an adventure to China, where he joins up with a band of martial arts warriors in order to free the imprisoned Monkey King." (Source: IMDb)
In recent interviews Jackie Chan and Jet Li tried to minimize the impact of this movie saying it was first targeting the American public. But to my viewpoint it's going to be a really good Kung Fu movie!
