The first collaboration between Jackie Chan and Jet Li opened with a roar at North American cinemas at the weekend - becoming the first martial arts movie to open at number one in four years.
The Forbidden Kingdom exceeded industry forecasts with its US$26 million in ticket sales.
Chan and Li play mentors to a modern-day kung-fu devotee who has been hurled back in time to rural China.
It's directed by Stuart Little maker Rob Minkoff and has been well received by the critics.
