How does the cinematography of Brokeback Mountain and Wyoming (aka Alberta, Canada) add what Larry McMurtry calls lyrical pastoralism?

When stories become screenplays, information (characters, scenes, setting, etc.) is added and deleted. For your major paper assignment, please read Brokeback Mountain; Story to Screenplay and view Ang Lees 2005 film Brokeback Mountain.
NOTE: Purchase the edition that contains the short story, the screenplay, and the three author essays! You will need to read the entire book AND view the film!
While reading and viewing, please take note of the differences in the literary mediums (changes and transformations from story to screenplay to film). Please point to specific passages and scenes, specific dialogue and relationships, and specific visual landscapes and scenery.
In your 1200 word response, you are required to analyze the following:

2. How does director Ang Lee augment Proulxs view on geographic determinism the belief that regional landscapes, climate and topography dictate local cultural traditions and kinds of work?
3. How does the cinematography of Brokeback Mountain and Wyoming (aka Alberta, Canada) add what Larry McMurtry calls lyrical pastoralism? In other words, how do the visual images of the landscape help shape the story and poeticize Ennis and Jacks relationship and reunion?
