Who Am I? is a Golden Harvest HK film but when it was released in the US it was cut by about 10 minutes and scenes rearranged to make it clearer to American audiences right from the start who the bad guys were. Follow this link to see the changes here. All the US, UK and Australian previous DVD releases of the film (and including both the versions on this Blu-ray disc) are of the shorter international version. In Hong Kong Region 2 the full 120 minute cut of the film was available some time ago.
