The 24-year-old actress, who is famed for playing Serena van der Woodsen in the glamorous TV show, stars in director Oliver Stone's drug thriller and she said that she loved the challenge it gave her, reported Contactmusic.
"I feel like all I've done lately is play really sexually-charged drug addicts. I don't know what's wrong with me. I've gotta go to Disneyland more and get more excitement. I love that it's so different from everything that I've ever known or seen. I love that challenge.
"I love exploring worlds that are so unknown to me. And having somebody like Oliver made it such a great experience because he gave us so many opportunities," Lively said.
The actress said that she made sure she did her research as she wanted to make her portrayal of O, the girlfriend of a marijuana grower who gets kidnapped, as realistic as possible.
"He (Oliver) gave us all the knowledge and information we needed. He brought people in, like DEA Agents. I met a little girl who had been kidnapped by the Mexican drug cartel. We met people in all areas of the marijuana field. Then, we also sat with each other - each character - and really rehearsed this movie," she added.
