Just found the running time of the UK version, which is 96 mins, the Jap DC bootleg I have clocks in at approximately 99 mins. So, given that the official release is PAL encoded and the bootleg is NTSC and there's a 4%(?) difference in the framerates, how is this calculated if I'm to find out that the bootleg is different from the official version?
Am I making any sense?

With regard to your version of The Killer, I'm afraid I'm no help there.
