You're helping bring a book to life that many people have grown to love and adore. Do you have any books that are similarly near and dear to your heart that you would love to see translated into a movie?
"When I was younger, I was a big fan of Enid Blyton's stories: Adventures of the Wishing-Chair and The Wishing-Chair Again. Much like Harry Potter, those books were magical, but in a different way. There weren't any wands or wizards, but it was still a fantasy.
There is an inevitable comparison of The Mortal Instruments to Twilight. Personally, we think Clary is a much more badass protagonist — do you agree?
"I agree. The thing about Clary that makes her different is that she is never a victim. She propels the story forward, and she isn't defined by the men in the story. The story is action and drama with a side of comedy. Clary can also be witty, which is important in a dark story."
What do you think it is about her strength that really sets her apart?
"Well, she goes on a single mission to save her mom, and that's her focus. It's totally badass because she's thrown all these love curves and she's still after the action."
The book series so far is looking at six titles, with an unknown amount of appearances by your character in any of the spin-offs that Cassie Clare is planning. Are you worried about getting tied down to such a big franchise?
"No, I was a huge fan of the books and I fell in love with the story and characters. I will be prepared to play Clary for as long as possible. But also, in something like this with sequels, you hope they continue to make them, but you can't really expect anything. I would rather just live in the moment."
What was the casting process like for you?
"Well, they came to me with the project, so I didn't have to audition. I read the first book and became obsessed. When I found out they were making a movie, I made phone calls and wrote emails asking how I could get involved.
So, what was it like the first time you read with Jamie?
"Well, I don't remember how many readings I had done before Jamie, but I knew that after he came we didn't need to see any more — Jamie literally stole the show! When we started acting I felt like the Clary I wanted to create was born. She came alive as Jace came alive. It was a really cool experience."
What’s the one product that can instantly refresh you or change the way you look?
"I love Lancome mascara. It lengthens and just makes my eye pop and look awake. It's especially helpful on busy days when I'm tired but need to look awake."
Got any other beauty secrets you swear by?
"I'm big on sunscreen. I learned that on Mirror Mirror. They were adamant about wearing a lot of sun protection and keeping my hands moisturized."
We heard you talking about your eyebrow's Twitter on Chelsea Lately. You seem to take it all in stride, but does it ever feel weird?
"Oh, it's totally weird. Very weird. It's become this mark, like it's 'my thing' — which is funny because everyone has eyebrows. It's ironic because I wasn't always confident about them when I was little and now they're my trademark. I think it's funny there's an entire Twitter account dedicated to one of my body parts, but you've got to laugh at it. It's not normal, but very complimentary."
We heard you’d tweezed your brows before and didn’t love it. Would you ever consider changing your gorgeous brow shape if the trend veered toward a less bold look?
"No, I don't care if it's a trend or not. It's part of who I am. I think maybe if a character role required me to I would consider it, but they're a part of my face. I wouldn't change them just because they weren't trendy anymore. I tweezed once when I was younger and it didn't go so well. I learn from my mistakes."
Crop tops seem to have become a staple in your wardrobe lately. Are they your current fashion obsession?
"Well, it's summertime everywhere we go, and I like crop tops. They're great in the heat. But honestly, they're lightweight and easy to pack. I had to bring about a million outfits on this press tour, and they take up less room in my suitcase."
What are some of your other style obsessions?
"I'm a big, big fashion girl. I love blush-tone pinks right now. I also love mixing fabrics. And cutouts in outfits! You know, showing some skin but keeping it classy. There's definitely a way to do it."
Who are your favorite designers?
"Alexander McQueen, Alexander Wang, Chanel, Topshop. I love Chanel. I'm also obsessed with Valentino!"
