Garden of Eden
This was based on a Hemingway novel which I haven't read.
It takes place in post WWI Europe and tells the story of a weak willed writer and WWI vet who meets and falls in love with a slightly androgynous and very bossy heiress. They get married. While honeymooning across Spain and France, his wife decides that they should take a third person into their marriage. The results are of course, mostly negative.

The wife is also jealous of her husband's writing while the husband has unresolved issues with his father, mostly shown in flashback in African safaris.

The writer is played by Jack Huston (Richard from "Boardwalk Empire"). Mena Suvari ("American Pie", "American Beauty") is the wife and Caterina Murino is the second wife.

I don't know if this was a problem with the source material but the story sort of lacked intensity. The wife never seems to have real motivation for her actions.

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
