There are just so may to choose from! Where to start? For me, these ones immediately come to mind:
1. The look Ennis gives Jack, as they are riding together after sorting out the mixed flocks of sheep, right after Ennis teases Jack about his harmonica playing. This is a subtle, yet powerful clue, as to how much Ennis has fallen in love with Jack.
2. The look Jack gives the bartender after Jimbo returns to the pool table. The way he looks so serious and moves his eyebrows to emphasize the point he was making about not being able to afford "a ropin' horse".
3. The expressions on both of their faces, during the Lake Scene argument, as they are face to face. The intensity, was so real, yet not melodramatic. I totally forgot that it was Heath and Jake ACTING in this scene. They had truly BECOME Ennis and Jack.
4. Alma's look of shock when she discovers "it".
5. Lureen's look, after Jack asks LaShawn to dance.
6. Ennis's expression when he comes back down stairs holding those shirts, and he looks at Jack's momma
as if to say. 'I would like to take these home with me'.
7. Jack's momma's 'knowing look' in return.
8. The "Jack, I swear...." scene. Chokes me up everytime.
