Shanghai Knights

Jackie Chan stars as Chon Wang, a Chinese sheriff who teams up with Owen Wilson's Roy O'Bannon to track down a killer in London, while also navigating their complicated past and a puzzle box that holds a family secret. Along the way, they encounter Inspector Artie Doyle, Fann Wong as Chon Lin, and help save the British royal family from assassination. The duo's chemistry makes for fun moments, but the plot has its flaws, leading to mixed reviews.
