O.C fans will know her as Kaitlin Cooper or Gossip Girl fans will know her as outspoken model called Agnes Andrews and in both shows she was no disappointment. I enjoyed her in both shows myself and she certainly adds something different which she will take with her to new superhero show 'Arrow' - Willa plays Thea Queen.
She told Jezebel Magazine: "The fact it was based on a DC Comics book, and the fact that I would get to play a superhero. I don't want to spoil anything... but every episode gets more and more awesome."
Willa plays the younger supportive sister of Oliver (leading character) and although she does not have to wear a superhero costume, she still wanted to be in good shape. She told Jezebel Magazine: "Now I do Pilates and just try to keep my body in motion-walking around doesn't really do enough, so I have to do something else."
Arrow is shown on SKY1 in the UK, Mondays at 8pm and I will definitely be watching it. - The trailer is below if you want to have a sneak peek to see if you might be interested.
