I was just thinking about the "I know" scene and how it was much longer and sappier than that originally. Did they film it in the original incarnation? I can't remember.

I'm pretty sure that version was filmed because there's commentary or interview somewhere of Kersh saying that they filmed it a few times with the sappier dialogue and none of them - Kersh, Ford or Fisher - felt like it was working. That was when Kersh told Ford "Don't think about what to say, just go with your gut" (or something to that effect) and that's when Ford came up with "I know".
