Oldman told Yahoo! Movies, "God bless him. Good luck, that's what I say."

Touching on the the character's persona as a "true blue" detective, Oldman said, "The thing you've just got to get used to with Gordon is he's a really sound detective, first of all. And he's really incorruptible, which is a kind of wonderful quality to play and sort of, like, true blue."

He added, "He's like a Watson, oddly. He's sort of like Watson to Sherlock, is Gordon to Batman."
