J.K. Simmons Is Trainning Hard For Justice League

Updated : June 09, 2016 04:43 PM IST

Oscar winning actor J.K. Simmons has undergone a surprising physical transformation in preparation for a superhero movie. An Instagram post by the actor's fitness trainer, Aaron Williamson, shows off Simmons' full beard and amazing muscles. The 61-year-old actor is supposedly training for his role in the next film in the D.C. Comics superhero series, Justice League, directed by Zack Snyder. He will soon reprise his role as Commissioner Gordon.

Every time we train together I forget he's 61 years old. So much respect for this guy. #JKSimmons #OldManCranking (hashtag via @mountaindog1)

Aaron Williamson, a self-described “U.S. Marine, actor, fitness pro” who’s previously worked with Zac Efron, Dwayne “The Rock” Johnson, Emilia Clarke (for Terminator Genisys, which Simmons also starred in), and, um, Hayden Christensen. Simmons previously said he plans on getting into character as Jim Gordon by “learning as much as I can about him through the comics and getting my feet wet in the first movie, and then hopefully continuing on from there.”

Simmons is perhaps better known for his wide-ranging career as a celebrated character actor in films like Juno and Spider-Man. In 2015, Mr. Simmons received the Oscar for Best Supporting Actor with his performance as sadistic jazz instructor Terence Fletcher in Damien Chazelle's Whiplash. Justice League is scheduled to be released on November 17, 2017.
