Amongst a flood of recent films about father-and-son reconciliation, Duckweed is the most playful, powered by the easy charm of two of China's most in-demand stars. After mis-timing a stunt in front of an oncoming train in 2022, arrogant rally driver Tailang (Deng Chao, the one-man environmental hazard from Stephen Chow's The Mermaid) is transported back to 1998 only to enlist in the gang of his ne'er-do-well father Zhengtai (Eddie Peng, taking a break from the gym to show his comedic chops). An existential crisis hits when Tailang realizes that his future mother isn't yet on the scene, even though she must get pregnant soon before his father is imprisoned for six years. Highlights of their familial bonding include a farcical bedroom seduction scene. The second feature by rally driver, singer and novelist Han Han, following metaphysical road movie The Continent, accelerated past the billion yuan ($150 million) milestone in China.
