There is a difference between being lucky and being good.People often mistake "Casablanca" as one of the greatest films of all time because director Michael Curtiz stumbled upon an ending he didn't have when he began the film.

Humphrey Bogart plays Rick, the owner of Casablanca's most popular café; a guy who "sticks his neck out for nobody." Rick looks like a wizened old prune, yet he seems to bed the cute French chickies faster than a mattress company. What exactly does Ilsa (Ingrid Bergman) see in old Rick? He expresses affection with a smirk, has all the emotional range of a lobotomized jackrabbit and seems to kiss like an inflatable doll.

The funniest thing about "Casablanca" is the premise that the letters of transit that Rick holds would actually get Ilsa and her underground leader husband, Victor (Paul Henreid) out of Morocco. Those Nazis may not be squeamish when it comes to killing Jews, but try to get them to rip up a couple of letters of transit at the border and apparently they develop ethics.

Certainly, "Casablanca" has some of the most memorable lines in film history, but again, here is where greatness needs to be distinguished from luck. The lines, like everything else, were changed at the last minute. Unearthed for the first time, here are the original lines as they were meant to be spoken.

LINE: "I stick my neck out for nobody."
ORIG: "I'm apolitical with a capital A."

LINE: "Of all the gin joints in all the towns in all the world...she walks into mine."
ORIG: (Bogart belches like a Rhino).

LINE: "Here's looking at you, kid."
ORIG: "Honey, you put the 'lust' in 'luster.'"

LINE: "I think this is the beginning of a beautiful friendship."
ORIG: "You know, Renault? For a fat guy, you got a nice booty."
