12 Most Radical Body Transformations For Comic Book Movies

10. JK Simmons - Justice League

Weight Gain: Unknown, but look at those pythons!

If there was one character in the upcoming Justice League movie that you'd probably give a free pass when it comes to intense gym-based preparation, it'd probably be JK Simmons' Jim Gordon. He's an older guy - a wise old head - and he's unlikely to be fighting anyone on the front-lines when there are Gods and superheroes to deal with the alien invasion.

Still, that didn't stop Simmons from taking the opportunity to feed his pythons and transform himself into Zack Snyder's dream vision of Gordon. The actor shared his new look on Instagram in the middle of a workout, revealing arms that a He-Man action figure would be envious of.

Hopefully we'll get to see him using that physique a little more in The Batman.
