I just finished watching BBM tonight and noticed something interesting in two crucial "wind" scenes. I don't recall if this has come up previously in this thread (forgive me if it has).
In the "morning after" scene following TS1 immediately after Jack says "see you for supper" the wind kicks up (this I know we've discussed in the past). But the thing that really struck me this time, is that the wind actually comes from behind his back and towards Ennis. The only effect this wind seems to have on Jack himself is that it ruffles the collar on his coat slightly. The wind almost seems to follow or line-up with his gaze looking at Ennis.
This is striking, primarily, because it happens again and in a more dramatic/ noticeable way when Ennis and Jack part ways at the end of the '63 summer. When they're both standing next to Jack's old truck... the wind is really whipping... and again it's essentially coming from Jack's direction and towards Ennis. In this scene, Ennis is squinting (in his normal way) and really seems to be battered by the wind coming towards his face (his squinting seems to be as much a result of the wind as the brightness of the sun). Jack however, appears almost completely un-touched by this wind... he almost seems oblivious to it. He's not squinting (in anywhere near the dramatic fashion that Ennis is) and the fact that the wind come from behind Jack's back causes it to have less of an effect on his comfort (apparently). And, then of course, once Jack leaves the wind remains to follow Ennis into the alley.
Truly amazing and very spooky. Jack is honestly a little spooky in many ways even from very early on in the film... Only to become more dramatically so as a "presence" following his death.
