“Mortal Instruments” star Lily Collins promises “heart pumping action”

The new trailer for Mortal Instruments: The City of Bones is just days away, and star Lily Collins promises fans “heart pumping action,” “great music” and “high energy” with the latest preview, The Hollywood Reporter said.

“It ends, and you have to watch it again because there’s so much packed into the trailer,” the actress tells The Hollywood Reporter. “The first time I watched it, I asked to watch it three other times just ‘cause it’s so much that happens, it’s like a whirlwind.”

Starring Collins, Jamie Campbell Bower, Robert Sheehan, Jonathan Rhys Meyers and Lena Headey, among others, the film is based on Cassandra Clare’s YA novel and tells the story of a teenager (Collins) who comes to learn of her own supernatural powers after her mother (Headey) is kidnapped by a demon.

“As well as hopefully pleasing the fans of the series, I think we're going to invite new people in and make them obsessed with the story as well,” Collins says. “I couldn't be prouder of the project. I'm so excited for people to see it. I really think Harald [Zwart, the director] did an amazing job of taking what could've been a CGI-heavy, action-packed film and really made it about heart and character and emotion. Special effects are just the icing on top.”

The film is slated to hit theaters on Aug. 23 with the second trailer and a new poster to be revealed at WonderCon on Saturday, March 30. It will be available online April 1.

City of Bones is the first of a six-book series by Clare. Asked if she’ll be back to reprise her role of Clary, Collins says she is happily contracted to continue the series, but will be eagerly anticipating a green light on a potential franchise.

In the meantime, Collins is busy promoting her two latest projects: The English Teacher (co-starring Julianne Moore, Nathan Lane and Greg Kinnear) and Stuck in Love (also opposite Kinnear). In May, she will begin filming Love, Rosie in Ireland with The Hunger Games: Catching Fire star Sam Claflin.
