Most people think Al Pacino said in the film “Dog Day Afternoon” the phrase “I’m dying over here”, but he actually said “I’m dying here”. It was Andrew “Dice” Clay doing an impression of Pacino in his “The Diceman Cometh” live show from 1989 that popularized “I’m dying over here” by adding the extra word, which sounds better anyway.

In the film “Casablanca”, Humphrey Bogart never said “Play it again, Sam” — he said “Play it”. However, Ingrid Bergman said “Play it once, Sam” and also “Play it, Sam”.

Cary Grant never said “Judy, Judy, Judy”.   Cary Grant himself said that he believed it was started by the actor Larry Storch doing an impression of him.  Grant said the name “Judy” a number of times in the film “Only Angels Have Wings”, but never “Judy, Judy” or “Judy, Judy, Judy”.  There’s no doubt it was popularized by George “Goober” Lindsey on “The Andy Griffith Show” when he does a purposely-horrible impression of Storch doing Grant with that same infamous line he never said.

Clint Eastwood in the original “Dirty Harry” film never said “Do you feel lucky, punk?”.  He said “You’ve got to ask yourself 1 question — do I feel lucky?  Well, do ya, punk?”  And he said it twice in that film & that’s it.  He had other catch phrase he tried to create with each Dirty Harry, and none of them stuck except for one which was the biggest of them all — in “Sudden Impact”, he said “Go ahead — make my day.”

There are lots more — Google them.
