The movie revolves around a kungfu-obsessed American teenager (starring Michael Angarano) who somehow time travels back to ancient China. There he meets with some martial art masters and join their quest to free the Monkey King, and presumably save the world too. Trailer here.
Frankly, I am not fond of the storyline, it sounds cheap. Still, having Jackie Chan and Jet Li in the same movie is enough to get me into the cinema. Hope it’s not a flop.
