In the book series, Elena is described as having blonde hair and blue eyes, different from the TV adaptation
Natural blonde Ashlee Simpson was the CW's first choice for the role of Elena Gilbert.
After a failed first audition, Nina Dobrev sent in a second tape, impressing the creators and winning the role.
Co-creator Kevin Williamson wanted an on-screen Elena who was more relatable, opting for a 'girl next door' appearance.
Brown hair and eyes were chosen to make Elena more relatable and to resonate with a wider audience.
Fans initially had a hard time accepting the changes, including Bonnie's appearance, Caroline's friendship, and Elena's brother.
Katherine, Elena's doppelgänger, was changed from German to Bulgarian, reflecting Dobrev's own ancestry.
Nina Dobrev's portrayal of Elena eventually won over author L.J. Smith and fans, earning praise for her acting skills.
