The Los Angeles-bred actor also showed body transformation in 2010’s fantasy movie Prince of Persia getting bulky and well-toned.

After Prince of Persia, Gyllenhaal again showed his body transformation in an impressive way but for the second time, it was a bit different.

For 2014’s thriller movie Nightcrawler, Jake Gyllenhaal showed off some shocking body transformation losing 30 pounds for the role as Lou Bloom. We saw the modification in the movie with Jake’s hollow cheeks.

The 36-year-old actor was sporting a much leaner look in the movie. From his 180 pounds body frame, he shrank down to 150 pounds. To embrace the look of the a wild-eyed paparazzo he ran 15 miles a day and really struggled physically.
