Robert De Niro: Murray Franklin
Arthur Fleck : How 'bout another joke, Murray?
Murray Franklin : No, I think we've had enough of your jokes.
Arthur Fleck : What do you get...
Murray Franklin : I don't think so.
Arthur Fleck : ...when you cross...
Murray Franklin : I think we're done here now, thank you.
Arthur Fleck : ...a mentally ill loner with a society that abandons him and treats him like trash?
Murray Franklin : Call the police, Gene, call the police.
Arthur Fleck : I'll tell you what you get! You get what you fuckin' deserve!
[Joker shoots Murray in the head, killing him instantly]
Arthur Fleck : I've been the man of the house for as long as I can remember. I take good care of my mother.
Murray Franklin : All that sacrifice, she must love you very much.
Arthur Fleck : She does. She always tells me to smile and put on a happy face. She says I was put here to spread joy and laughter.
Murray Franklin : [from trailer] All that sacrifice, she must love you very much.
Murray Franklin : Do I understand that you did this to start a movement? To become a symbol?
Arthur Fleck : Oh come on, Murray. Do I look like the kind of clown that could start a movement? I killed those guys because they were awful. Everybody is awful these days. It's enough to make everyone crazy.
Murray Franklin : Okay, so that's it? You're crazy, that's your defence for killing three young men?
Arthur Fleck : No. They couldn't carry a tune to save their lives.
Murray Franklin : And finally, in a world where everyone thinks they could do my job, we got this video tape from Pogo's Comedy Club right here in Gotham. Here's a guy who thinks if you just keep laughing, it'll somehow make you funny. Check out this joker.
Arthur Fleck : You're just like the rest of 'em!
Murray Franklin : You don't know the first thing about me, pal. look at what happened because of you did. what it led to. there are riots out there, two police men are in critical condition- you're laughing, you're laughing. someone was killed today because of what you did.
Arthur Fleck : I Know!
Murray Franklin : Look what happened because of what you did, what it led to! There are riots out there! Two policemen are in critical condition...
[Joker starts to chuckle]
Murray Franklin : ...You're laughing. You're laughing. Someone was killed today because of what you did.
Arthur Fleck : [guffaws] I know.
