Who makes more eye contact, Jack or Ennis?
I would have said "Jack" without hesitating, except that I just finished watching the DVD all the way through (made it to the end for the first time since buying the DVD, and started crying at the second tent scene, dammit). And it struck me that, although Jack makes a lot of eye contact when he's not talking (or leaving things implied; see the post-divorce scene, or when Jack is trying to pick up Jimbo the rodeo clown), that he usually looks away from Ennis when Jack is saying something that's really important to him. (Examples: Jack looks off at nothing, face as impassive as he can make it, when he proposes the cow and calf operation. And he doesn't look at Ennis when he tells Ennis that sometimes he misses Ennis so much he can't stand it.)
The big exception is in the fight scene at the lake... there both Jack and Ennis look straight at one another. And then Jack says what's on his mind. (Though they break eye contact during Jack's big speech.)
Ennis avoids looking at people as much as he can, it seems. But when he wants to make a point, especially with Jack, Ennis looks right at him. I think. But I can't remember the examples now.
Anyway. That just struck me.
