The Cincinnati Kid (1965)

Other mistake: Just before Ladyfingers starts as the dealer in the big poker game, we are shown how skilled she is, with a close-up of her hands doing an expert shuffle of the deck. Lancey even tells her she hasn't lost her touch. But then she deals the third and fourth cards so badly that they flip in the air and are easily seen as a red deuce and a black deuce. It happens toward the bottom of the screen but slowing down the DVD makes it obvious.

Deliberate mistake: During the funeral march you can see that one of the guys dancing has 1960s-style sunglasses on.

Deliberate mistake: When The Kid visits the farm, the red truck in the background is a Fleetside truck that is definitely not from the 1930s.

Cincinnati Kid: Listen, Christian, after the game, I'll be The Man. I'll be the best there is. People will sit down at the table with you, just so they can say they played with The Man. And that's what I'm gonna be, Christian.
Christian: I know.

Lancey Howard: Gets down to what it's all about, doesn't it? Making the wrong move at the right time.
Cincinnati Kid: Is that what it's all about?
Lancey Howard: Like life, I guess. You're good, kid, but as long as I'm around you're second best. You might as well learn to live with it.

Slade: How the hell did you know I didn't have the king or the ace?
Lancey Howard: I recollect a young man putting the same question to Eddie the Dude. "Son," Eddie told him, "all you paid was the looking price. Lessons are extra."
