Mortal Instruments author Cassandra Clare and director Harald Zwart share how they brought the beloved book to the big screen, while Mad Men's Jared Harris reveals why he wanted to be a part of the highly anticipated YA adaptation.
"They just had a first screening for fans and I ran into some fans that have been fans for a really long time," said Clare. "They were like, 'We love it!' And when they told me that they loved it … the fact that they loved it meant the most to me."
