Earlier this month, a picture of JK Simmons suddenly looking incredibly muscular spread like wildfire around the internet. Stood in the gym, with a bushy beard and clenching two dumbells, the 61-year-old actor’s veiny biceps bulged. We’d never seen him like this before.

Fans widely speculated that it was for his new role in Zac Snyder’s new comic book film Justice League. Simmons is playing Commissioner Gordon, a character usually seen in a suit, but it would surprise few if a director like Snyder, who’s also responsible for the films 300 and Man of Steel, would insist that even his honest cop (played by Gary Oldman in Christopher Nolan’s Batman series) be ripped.
