http://docs.com - Gyllenhaal 32 really wanted to say no to Prisoners. Blame the acclaimed 2012 movie called End of Watch in which he also played a cop.I had done so much research to play that previous role and had immersed myself for so long into that world he says with a sigh. Honestly I thought I might want to explore something else.Luckily we ended up going to a whole different place with Prisoners. Playing a detective working on a double kidnapping case meant that his own motives were divided.You have to walk the line between being fascinated and infatuated with the mind of the criminal he says.At the same time you have to care so deeply about the victims.You cant show the victims how much you actually care because you have to follow protocol.
