I think we can all appreciate the lighthearted and hopeful ending of this film that made it to the big screen when compared to the ending from the original script that did not go over well with test audiences.
In what is now considered the "alternate ending", thanks to the scene being featured on the Blu-ray/DVD, we see the film conclude with the gut-punching sequence of Chris ending up in prison for the murder of Rose and her family — despite his actions being purely self-defence.
This original ending came from Peele's need to address that we're not living in a post-racial world, telling BuzzFeed, "The ending in that era was meant to say, 'Look, you think race isn’t an issue? Well at the end, we all know this is how this movie would end right here.’"
