I must rewatch it because I definitely did NOT hear anything about Jacob's name change, but things were flying by sort of out of context that if one didn't understand the whole story, one would certainly wouldn't know it after watching the program.
Especially, most non-bible readers or students of the bible wouldn't bother to watch this moe than once.
OK I watched the first half again real close. Several things. First of all Sodom. In the background scenes in the shadows was the sin including a man dancing or embracing his sheep. It also showed Sodom to be a pretty corrupt people when Lot was taken captive there earlier and rescued by Abraham.
The narrator in the movie did give bloodline of Abraham, Isaac, and Jacob whom GOD would rename Israel. This explanation came after the test of sacrificing Isaac. They did explain that part but did not make Jacob's story a scene in the movie itself.
