One thing I noticed -- maybe it will seem petty -- but, for all her glamour and glitz, fancy clothes, jewelry, Daddy with the $$$$... see the picture just above... her nail polish is chipped! To my mind, like I say maybe I'm being petty but, it just demonstrates that Lureen is all show, she forgets the small, fine details. Maybe she just ignores them... As long as she looks rich and pretty at a quick glance, that's enough. Look any further and you find a woman who is unhappy, depressed, lonely. I've always thought that, all the years she and Jack were married, on one level she thought she was In Charge, if you know what I mean... she pursued him, she had the rich daddy who got him a job and all, she probably thought he needed her... and on another level maybe she wasn't so sure, she didn't know his friends and didn't understand his 'fishing trips' and so forth. And then Jack gets killed, maybe she knows why, maybe not. And the phone call from Ennis confirmed her worst fears... that Jack HAD had a life apart from her... in truth, he had never been hers, really, not at all. You see the realization hitting her, the tears welling in her eyes. Her entire marriage had been a facade.
It was an incredible performance by Anne and I think you stated exactly what it was all about. Great observation pierralex.
