He has done a lot of different types of roles throughout his career and he is amazing at whatever he does. I know most people probably know him from donnie darko or brokeback mountain. I found out about him around 2005 with jarhead a slow burn movie and Gyllenhaal is fantastic in it. Other movies like Prisoners. Zodiac, Nightcrawler, Southpaw all good movies. Nightcrawler in particular I thought was his best work to date. He made me believe that he was really that crazy guy. Then he comes back and does southpaw and he makes me believe he is this really badass boxer. He can do any role he sets his mind to and knocks it out of the park everytime. Thoughts?
