Jeremy Gilbert Didn't Exist in the Source Material
When the series was announced, there was even more controversy when Elena's four-year-old sister Margaret was replaced by an angsty teenager in Jeremy Gilbert for the TV adaptation.
Aunt ... Judith?!?
Aunt Jenna is named Judith in the book series, so that was changed for some bizarre reason from page to screen.
From Enemies to Friends
Another big change in the series is that Caroline was a friend for Elena as opposed to an enemy.
Matt's surname in the book series is Honeycutt as opposed to Donovan in the series. On top of that, he has no relation to Vicki in the book series.
Zach Roerig Almost Played a Salvatore
Matty Blue Eyes was almost more interesting.
Michael Trevino Almost Played a Salvatore
He went on to play Tyler Lockwood, of course.
