Cinematical has just received this exclusive poster for The Forbidden Kingdom, otherwise known as the film that pairs up martial arts veterans Jackie Chan and Jet Li for their first ever big-screen collaboration. Directed by Rob Minkoff (The Lion King), The Forbidden Kingdom follows an American teen (Michael Angarano) and all-around Kung Fu nut, who comes across a mysterious Chinese staff that transports him back to ancient China. While there, he meets up with two Kung Fu masters (Chan, Liu Yifei) and the Silent Monk (Li), and the four head off to fulfill an ancient prophecy to free the jailed Monkey King. Of course, there's another set of warriors who will attempt to make their journey just a wee bit difficult. Not long ago, a teaser trailer premiered announcing the end of principal photography, and the footage looked pretty insane. The Forbidden Kingdom will arrive in theaters on April 18.
