Brett Cullen: Thomas Wayne
Thomas Wayne : What kind of coward would do something that cold blooded? Someone who hides behind a mask. Someone who is envious of those more fortunate than themselves, yet they're too scared to show their own face. And until those kinds of people change for the better, those of us who made something of our lives will always look at those who haven't as nothing but clowns.
Thomas Wayne : [after punching Arthur] Touch my son again and I'll fucking kill you!
Thomas Wayne : Gotham's lost its way.
Thomas Wayne : Can I help you, pal?
Arthur Fleck : I don't know what to say.
Thomas Wayne : Do you want an autograph, or something?
Arthur Fleck : No. My name is Arthur. Penny Fleck is my mother.
Thomas Wayne : Jesus. You're the guy that came to my house yesterday.
Arthur Fleck : Yes. I'm sorry, I just showed up. But my mother told me everything, and I had to talk to you.
Thomas Wayne : Look, pal, I'm not your father. What's wrong with you.
Arthur Fleck : Because I think you are.
Thomas Wayne : Well, that's impossible. Because you were adopted, and I never slept with your mother. What do you want from me? Money?
Arthur Fleck : No, I don't. I wasn't adopted.
Thomas Wayne : Jesus, she never told you?
Arthur Fleck : What?
Thomas Wayne : Your mother adopted you while she was working for us.
Arthur Fleck : That's not true. Why are you saying that?
Thomas Wayne : But she was arrested and committed to Arkham State Hospital when you were just a little boy.
Arthur Fleck : Why are you saying this? I don't need you to tell me lies! I know it seems strange! I don't mean to make you uncomfortable! I don't know why! Dad, I just want a little bit of fucking decency! What is it with you people? You say that stuff about my mother!
Thomas Wayne : She's crazy.
Arthur Fleck : She's...
[Starts laughing uncontrollably]
Thomas Wayne : You think this is funny? Is this a joke to you?
Arthur Fleck : [still laughing] Dad, its me! Come on!
Thomas Wayne : [punches Arthur in the face] Touch my son again, I'll fucking kill you.
Thomas Wayne : What kind of coward would do something that cold-blooded? Someone who hides behind a mask?
Good Morning Host : [Arthur and Penny are watching the news about the three Wayne Enterprises businessmen that Arthur shot and killed on the subway] There seems to be a groundswell of anti-rich sentiment in the city. It's almost as if our less fortunate brethrens are taking the side of the killer.
Thomas Wayne : Yes, that is a shame. It's one of the reasons why I'm considering a run for mayor. Gotham's lost its way.
Good Morning Host : What about the eyewitness report of the suspect being a man in a clown mask?
Thomas Wayne : Well, it makes total sense to me. What kind of coward would do something that coldblooded? Someone who hides behind a mask. Someone who is envious of those more fortunate than themselves. Yet they're too scared to show their own face. And it's those kind of people that change for the better, those of us who've made something of our lives, will always look at those who haven't, as nothing but clowns.
Penny Fleck : [Arthur laughs] Penny Fleck:
Penny Fleck : That's not funny.
