It’s Jean Valjean declaring his identity as former prisoner 24601 to his nemesis Javert in the musical version of Les Miserables.
Another good Walken one is from The Prophecy:
- Gabriel: I’m an angel. I kill firstborns while their mamas watch. I turn cities into salt. I even, when I feel like it, rip the souls from little girls, and from now till kingdom come, the only thing you can count on in your existence is never understanding why.
Ideally, while tearing his shirt open like Superman.
Pavel: Gant, can you fly that plane? Really fly it?
Mitchell Gant (Clint Eastwood): (beat) Yeah. I can fly it. I’m the best there is.

My name’s Jim, but most people call me… Jim. I used to be known as The Waco Kid.
Does this count:
“HULK, SMASH!!!”
I like Tom Baker’s version:
“You may be a doctor, but I’m the Doctor. The definite article, you might say.”
Not nearly so over-written.
There are some who call me… Tim.
“Do you know who I am? I’m Moe Greene. I made my bones while you were going out with cheerleaders.”

Speaking of whom… “I am Elmer J. Fudd, millionaire. I own a mansion and a yacht.”
D’oh!
Speaking of millionaires…
“Hello, my name is Mister Snrub! And I come from…someplace far away! Yes, that’ll do.”
“I am NOT an animal! I… am a human being!”
That’s one I was thinking about.
My name is Oliver Queen.
Call me Ishmael.
My name’s Johnny, and it might be a sin
I’ll take your bet, you’re gonna regret
I’m the best there’s ever been.
“I am the Whistler, and I know many things, for I walk by night. I know many strange tales, many secrets hidden in the hearts of men and women who have stepped into the shadows. I know the nameless terrors of which they dare not speak.”
“And God said unto Moses, I Am That I Am: and he said, Thus shalt thou say unto the children of Israel, I Am hath sent me unto you.”
“Hello, I’m Troy McClure! You may remember me from such films as…”
I’m a little teapot, short and stout!
