UPDATE: But wait! J.K. Simmons later clarified that he's not actually getting this buff for "Justice League." Here's his update.

Original post:

Daaaaaamn. Oscar-winner J.K. Simmons is breaking out the big guns to play Commissioner James Gordon. The 61-year-old actor seems to be training Hugh Jackman-style for his role in the DC Comics movie "Justice League."

Simmons has been working out with celebrity trainer/U.S. Marine Aaron Williamson, with the teacher sharing proud photos of his star pupil. "Every time we train together I forget he's 61 years old. So much respect for this guy," Williamson wrote.

Check out some photos:

Saturday morning, 61 years old & making the young generation jealous. This is what dedication looks like. #JKSimmons

Gary Oldman never trained this hard when he was Gordon. Just saying.

"Justice League," directed by Zack Snyder, will bring together Ben Affleck's Batman, Henry Cavill's Superman, Gal Gadot's Wonder Woman, Ezra Miller's The Flash, Jason Momoa's Aquaman, and more, with Part One coming out November 17, 2017 and "Justice League: Part Two" currently scheduled for June 14, 2019.
