Collins: Instruments movie is dark
Lily Collins has said her Mortal Instruments movie is "sexier" than other young adult adaptations.
The actress plays Clary, a teen girl with special powers, in fantasy film The Mortal Instruments: City Of Bones, which is based on the first book of The Mortal Instruments series by Cassandra Clare.
Speaking at Comic-Con, she told The Hollywood Reporter the film is "really dark".
She went on: ""There's humour in it, which I think makes it different than any other franchise. It has a comedic undertone. But the world is darker than some of the teenage franchises that we've seen. It's very goth and underground. So, probably not for the youngest viewers.
"I think it will appeal to them because the boys having their action sequences, but I definitely think it will appeal to the older groups because it's sexier."
Lily said Clary's skimpy outfit helped her get into character: "It was awesome because Clary gets to go from being this normal teenage girl who dresses in boyfriend jeans and combat boots and leather jackets, and then all the action starts, and she wears tight leather pants, a dress that is basically a top it's so small and then five-inch thigh-high boots.
"I didn't practise any of my stunts in my costume. So all of a sudden, I'm thrown in to running up stairs and crawling at four in the morning in this outfit. But it was all worth it because I loved playing that bada**, sexy, dominatrix-y fighter character."
The action adventure film - which also stars Lena Headey and Jonathan Rhys Meyers - is due out in August and Lily will start shooting the follow-up later this year, and she said she is keen to make as many movies in the franchise as she can.
"There's way too much to be told to cram into one," she explained. "That's why it's so hard when you're taking a franchise of books and making them into a movie because at first you think there's only one shot. You hope there's more, but everything has to be so concise. There's so much to be told."
