re: Movie quote that gives away the film without saying the title

Hell, just about every movie worth watching has some quotes that give it away immediately. Some that come to mind are:

"What we have here is failure to communicate."

"I see dead people"

"I'm afraid the strain was more than he could bear."

"I'm your huckleberry."

"Badges? We don't need no stinkin badges,"

"We're on a mission from God."

"Hasta la vista baby."

"I'm mad as hell and I'm not going to take it anymore."

"I'm a Mog, half man, half dog."

"Who are these guys?"

"Hell, the fall will probably kill you."
