Zack Snyder: Justice League

Batman: "I've been dead inside a long time, but even I have a limit. And if you cross that line, I swear to God, I will ..."
The Joker: "Before what, Bruce? Kill me? You won't kill me. I'm your best friend. Besides, who's gonna give you a reach-around?"

"We live in a society, where honor is a distant memory. Isn't that right... [shows himself] ... Batman?"

Superman: "How did you get the house back from the bank?"
Bruce Wayne: "I bought the bank."

"Tell him to respect the storm next time."

Wonder Woman: "You said the age of heroes would never come again."
Bruce Wayne: "It will. It has to."

Barry Allen: "You have a satellite?"
Bruce Wayne: "I have six."

Alfred: "How do you know your team's strong enough? If you can't bring down the charging bull, then don't wave the red cape at it."
Bruce Wayne: "You do when it's this red cape. This red cape charges back."

"Everyone, this is Alfred. I work for him."
