Uncle Benny Chan was the secondary antagonist in Lethal Weapon 4. He was the kingpin of a powerful Los Angeles Triad gang and was responsible for the illegal human trafficking of Chinese slaves to the United States, in particular, the Hong Family.
Uncle Benny was in his restaurant meeting with Proody, a immigration consultant regarding the importation of immigrants from China. When his assistant reports that the cargo ship was impounded, Uncle Benny is most disappointed and he tells Proody that he has to go. The consultant is killed by a train later that night.
Benny is later visited by Team Riggs/Murtaugh and Lee Butters. The detectives believe Uncle Benny is responsible for the Chinese slaves being brought to the docking bay the other night, but Benny lies and says he doesn't know anything about it. He tells them he is very busy and forces them to leave, since they don't have any probable cause. Then Riggs shoots the transparent glass when Benny politely showed them the door. He also pulls the fire alarm, which sets off the sprinkler and gets Benny soaked.
A couple of days later, while Benny has a dental appointment, Riggs, Murtaugh, and Butters return to see him and come up with a way they can get him to talk more about the slaves and the Hong family. Refusing to talk, the trio use laughing gas within the room to extract the truth from him. Uncle Benny is forced to give in because of the gas.
Later, at the site of a warehouse, the Chinese kingpin grabs a paper full of counterfeit Chinese money and proudly smiles at it. Uncle Benny would meet his demise when he is strangled by Wah Sing Ku with a ligature because he had revealed the plan to Riggs, Murtaugh, and Butters. When the detectives visit the crime scene, Riggs looks at his dead body and noted how he was "actually starting to like the old goat."
