The 32-year-old, known for taking on complex roles, plays detective Loki in "Prisoners", reports contactmusic.com.
"I look for something in the story that offers love in a more complicated way. I don't look for darkness, whatever that means, but in my mind, darkness acknowledges great light too," Guardian newspaper quoted Gyllenhaal as saying.
"I think when it comes to a character, I'm moved by folk that I might struggle to love at first; characters that I have to do enough research on and think enough about to be able to really fall in love with them. Recently, in particular, that's what's been happening. I love Detective Loki. I found it hard to let him go," he added.
He also said that he spends a great deal of time researching about his characters.
