I was thinking fictional, but anything that seems to fit delta is welcome.
TV show:
The Rifleman
LSE maybe? Only saw one episode but the theme seemed decidely delta. The protagonist throws out Te left and right while stressing Ne and Fi ideals.
Movies:
All Roads Lead Home
Less so the characters as the movie itself (though I thought the grandfather was ExTj and there are likely other deltas in the cast). I'll warn you, it is not a good movie if you look into it. The only notable thing besides that it seemed delta was the fact that the movie was filmed within about 50 miles of where I live. It also won some kind of film award, but I suspect foul play.
Anyway, I'll add more if I think of anything.
