So I discovered this article today: https://www.animatedtimes.com/disney-announces-release-date-and-gives-new-teaser-of-the-lion-king-during-oscars/. I'm not sure whether it's a credible source, but it's worth some discussion.
Basically, it claims that Mufasa and Scar will not be brothers in the upcoming remake. The change was made to better mimic nature, where two unrelated lions can live in the same pride.
Personally, I don't like this change. I think Scar is a much more menacing villain as someone whom Simba is close to and trusts. Without that bond, the relationship loses a lot of resonance.
Thoughts?
