Morgan Freeman’s role in The Story of God was a personal one, as the subjects of religion and spirituality intrigue him greatly, and not just because he’s played God before.
If you watched Season 1, you no doubt marveled at how beautiful the series looks, as all the countries Freeman traveled to are captured so pristinely, but you might not have internally considered what it must have been like for Freeman to go to so many different places to talk about religion, which is a difficult topic to bring up in nearly any setting.
Sure, he’s part of a TV show, so it’s not like he’s going out all touristy, but Freeman is still enveloping himself in different cultures in the public eye, which could easily result in confusion and confrontations.
