Only once the dates are confirmed do they begin to think about a script. For First Strike, director Stanley Tong came up with a storyline, then flew to Canada to check out locations. Shooting began in August and wrapped up in January, and with the finished product due by early February, there were just two weeks left for post-production work.
於是唐季禮想出故事大綱，就去加拿大看外景，八月開拍，一月拍完，二月初就要交最後成品，後製作只有二星期時間，《簡單任務》就是這麼完成的。
