AnnaLynne McCord
In 2008, she was the eighteenth actress to be cast in The CW series "90210", portraying antiheroine Naomi Clark. Initially, the part of Clark was conceived as a supporting role. However, by the end of the first season, media outlets had begun referring to McCord as the series' lead. For the role of Naomi Clark, she was nominated for a Teen Choice Award and received the "Hollywood Life" Young Hollywood Superstar of Tomorrow award in 2009. In 2010, she won a Breakthrough of the Year Award in the category of "Breakthrough Standout Performance".

She competed with five other actresses for the part, but she believed that the role was meant to be hers, as Naomi is both her grandmother's name and her middle name. O'Rielly also said, "When I got the scripts, I really loved how Naomi works on lots of levels at all times. That is extremely satisfying to play as an actor." A week after the second audition, O'Reilly's agent informed her that she had won the role. She and her husband then relocated to Melbourne from Sydney to be closer to the studios. O'Reilly was initially offered a three year contract, but she felt that was too long and suggested an 18 month contract instead, which produces agreed to. O'Reilly began filming her first scenes in November 2013 and she made her screen debut as Naomi on 25 March 2014. In July, O'Reilly took two months off from filming in order to perform her one-woman show at the Edinburgh Festival Fringe. The break was agreed upon when O'Reilly got the part and she was thankful to the producers for giving her the time off.
