Connor MacLeod: Life brings hope and pain, but revenge never brings redemption.
Jacob Kell: Look on the bright side, at least you went down swinging.
Jacob Kell: What you need to understand is that I don't care about the game. I don't care about the rules. I don't even care about these pathetic souls you keep locked away as a barrier to the prize.
Kate MacLeod: Until the day we are reborn.
Jin Ke: Men, for the most part can mend their ways only after they have made a mistake.
Jacob Kell: A woman is a temple built on a sewer.
Kate MacLeod: Stealing's wrong. Lying's wrong. Killing's wrong. What you did goes well beyond wrong.
Duncan MacLeod: Fine I deserve that but I want a chance to make it right.
Kate MacLeod: You want to make it right? Then give me back the ability to have children, to grow old with the man I love. How about anything that resembles a normal life? And you took it all away from me.
Answer: The scenes you mention were only meant to be part of the trailer. This was to show that Jacob Kell was the "most powerful" immortal yet. The 'cut in half' scene is playing on the idea that Kell is unbeatable. I suggest rewatching the trailer with these ideas in mind. It may make more sense. These scenes were what Dimension Films wasted a hefty portion of the promotional and marketing budgets on. There was NEVER any script written that included them, nor any version of the film that ever included them.
