Gordon is one of the oldest and best-known characters in the Batman universe, having first shown up in the Dark Knight’s initial appearance in Detective Comics No. 27 in 1939. He became tied to Batgirl in the 1960s when she was introduced simultaneously in the comics and the Adam West television series as Gordon’s daughter, Barbara Gordon, an employee at the Gotham City Public Library. In more recent times, with expanded or rebooted multiverse storylines, Gordon has either been Barbara Gordon’s father or uncle-turned-adoptive father.
Simmons was cast as Gordon by Zack Snyder for 2017’s Justice League and appeared in added material for the filmmaker’s recently restored cut, Zack Snyder’s Justice League.
I feel that Jeffrey Wright would have made more sense but apparently this is not part of thesame continuity as The Batman movie.
Great news, when I heard they might cast another Gordon I was bummed, when we already have new Gordon in Pattinson's Batman movie, keeping J.K. is wise move, not because he's great actor but also keeping some continuity with Snyder-verseis importantin ordernot to make fans superconfused and tired with another recast, even though they aresorta rebooting DC universe with Flash movie it's still good news.
