ARegarding violence, the British DVD is completely uncut.
Furthermore, the British DVD features different opening credits. The difference starts with the scene in which Kit Li is screaming desperately. Here, the picture freezes in the British version; then, the English credits are faded-in in white writing on a red background. On the Australian VHS, the wreckage of the burning bus is shown again; then, Kit Li is dragged away by his colleagues. In the background, the narrator says "Explosives expert Kit Li loses his wife and son in an explosion. He quits the service. Two years later in Hong Kong"; the sentence is faded-in in Asian letters as well. Subsequently, one sees further shots of the burning bus. A detailed comparison between both versions with pictures can be found here.
