Nina Dobrev first caught audience's attention with a role in the horror musical Repo! The Genetic Opera in 2006. The unconventional film endeared her to a cult audience, but she soon followed it up with more conventional fare, joining the cast of Degrassi: The Next Generation. She would play teen mother Mia Jones on the show until 2009, and also appeared in other projects like the drama Away from Her, and the dance movie How She Move. In 2009, Dobrev was cast in one of the leading roles in the series The Vampire Diaries. ~ Cammila Albertson, All Movie Guide
