They changed the music too. I swear Heroes by Tove Lo was playing in the original....
I meant plot-related ones. Other changes were simply inclusions of like 0.5-second clips or different angles of the same things we've seen (Girl abut to get run over by the lawnmower, the Chanels storming down a hallway, the dead security guard falling, the dead woman in the bathtub after giving birth). I didn't really pay much attention to the music
Other than removing Cathy's brief ass appearance in the flashback, the other relevant difference from the upfronts trailer is they removed the clip of Grace saying "This isn't 1995 anymore" to her dad. That wasn't in the trailer that leaked earlier, either.
