Being new to this, I've enjoyed reading this thread. Whilst I know it really doesn't matter what they said, it's lovely watching it over and over again trying to figure it out. And I agree with what I read somewhere on this forum, that Ang Lee may have done this intentionally, letting us all give it our own interpretation.
The great thing about watching these clips so many times, is that you often see or hear something new. I really thought this scene couldn't get any sexier, but what I hear Jack saying (and the volume needs to be LOUD) just sends this scene off the scale as far as I'm concerned.
For the record, this is what I hear:
As Jack is going towards Ennis for the kiss he whispers "Come on" (oh my, oh my....)
As Jack starts to kiss Ennis he says in a kind of breathy exhalation "Go on, go on" (oh my, oh my, oh my.....)
After the kiss he says "it's allright" three times. (Oooohhhhhhhhh myyyyyyyyyyyyyy.........................)
