On May 10, 1973, Lee collapsed during an automated dialogue replacement session for Enter the Dragon at Golden Harvest in Hong Kong. Suffering from seizures and headaches, he was immediately rushed to Hong Kong Baptist Hospital, where doctors diagnosed cerebral edema.
On July 20, 1973, Lee was in Hong Kong to have dinner with actor George Lazenby, with whom he intended to make a film. According to Lee’s wife Linda, Lee met producer Raymond Chow at 2 p.m. at home to discuss the making of the film Game of Death. They worked until 4 p.m. and then drove together to the home of Lee’s colleague Betty Ting Pei, a Taiwanese actress. The three went over the script at Ting’s home, and then Chow left to attend a dinner meeting.
Later, Lee complained of a headache, and Ting gave him the painkiller Equagesic, which contained both aspirin and the tranquilizer meprobamate. Around 7:30 p.m., he went to lie down for a nap. When Lee did not come for dinner, Chow came to the apartment, but he was unable to wake Lee up. A doctor was summoned, and spent ten minutes attempting to revive Lee before sending him by ambulance to Queen Elizabeth Hospital. Lee was declared dead on arrival, at the age of 32.
Autopsy reports, Lee’s brain had swollen considerably, from 1,400 to 1,575 grams (a 13 percent increase). The autopsy found Equagesic in his system. On October 15, 2005, Chow stated in an interview that Lee died from an allergic reaction to the tranquilizer meprobamate, the main ingredient in Equagesic, which Chow described as an ingredient commonly used in painkillers.
