What was the last thing James Cagney Said??

No, no; that was from WHITE HEAT: "Made it, Ma! Top of the world!"

Just to clarify the matter. Tom Powers (Jimmy Cagney) says "I ain't so tough" AFTER the shootout in the building with the "bad" guys. He staggers out of the building into a heavy downpour, staggers along a bit, and then, before falling down into the gutter, he says "I ain't so tough." Great movie, great scene, great actor. What more could you ask for? Nuttin.

The last lines Cagney had in "The Public Enemy" were in the hospital. I'm watching the scene as we speak.

Here is how it goes:

Ma Powers: Tom, do you know me? Tommy boy?
Tom: Sure Ma.
Ma: Mike's here, he's come to see you.
Tom: Hi Mike.
Mike: How are you Tom, old scuff?
Tom: I've been wanting to see you.
Mike: You're going to be seeing a lot of me, Tom.
Tom: There's something I wanted to say to you, Mike. I'm sorry.
Mike: Sorry? For what?
Tom: I'm just sorry. You know.
Ma: You and Mike are going to be friends again?
Tom: Sure. Friends.
Ma: I'm so happy.
Tom: Ma, you must like Mika a lot better than me.
Ma: No, no, Tommy boy. You're my baby.
Tom: Sure. I'm your baby.
Ma: You're coming home, ain't ya Tommy? To stay?
Tom: Sure. Coming home. I mean, if I can ever get out of here.
Mike: You're gonna get out of here all right, Tom.
Ma: Why, of course you are. You're going to get well and strong. Both my boys back. All of us together again. I'm almost glad this happened.

And that's the end of the scene. His official last line? "I mean, if I can ever get out of here." There you have it.

"Listen to them, children of the night. What music they make!" -- Dracula (1931)

it only makes sense if you want his character to have learned nothing his whole life.
he just took out all those guys and got shot up for it, he realized finally that hes not the biggest or baddest.. thats why hes so remorse in the hospital and he finally gets back with his family. he aint so tough anymore.

Yes, csu, that's right. That last scene was really powerful/horrible! We've been seeing the situation through the eyes of his mother and brother, so happy that the gangsters are bringing him home...when the brother opens the door, there is poor Cagney, in his bandages, with his dead, open eyes..what a horrible sight for a mother or brother [a blessing Mom was upstairs]. That really got me.
