The new Batman themed Justice League teaser trailer featured not only new looks at Batman's Batmobile, fighting parademons, and the tactical Batsuit but also slipped a glimpse of J.K. Simmons as Commissioner Gordon into the tease. The quick glimpse is from J.K. Simmons' first day on set as the character. Gordon is standing atop the Gotham City Police Department, Bat-signal shining brightly into the sky, as he waits for Batman and some of his super friends to show up.
