Little was varying over the years, according to the 2003 screenplay:
118 EXT: MOUNTAINS: NIGHT: 1980: 118
JACK plays harmonica around the campfire. ENNIS drinks from whiskey bottle.
Same poor food, cans with spoons in them, beer bottles, whiskey bottles.
ENNIS looks mostly the same, elder, but still skinny.
JACK, the shorter of the two, has thickened some through the shoulders.
They aren't fishing. Just sit near one another, enjoy the country, the night, the fire.
WE SEE JACK in a down jacket. ENNIS in shirtsleeves.
JACK
Don't you never wear a coat?
ENNIS
(grin)
When it's cold.
Seems like spring to me.
JACK
It may be spring where you're sittin', but two
feet west, it’s goddamn winter, I tell you.
