Unbreakable is my all-time favorite twist ending. It packs such a stiff emotional punch that in the moment Jackson's character reveals why he did everything you're both horrified and heartbroken.

"It was the kids...they called me Mr. Glass."

I get chills every time I hear that line.

Some of my favorite surprise endings: The Others, Identity , Taking Lives, The Prestige, American Beauty (more of the shock maybe), Memoirs/Remember Me (the script, it hasn't came out yet, mind blowing twist ending) as well as Unbreakable, and Sixth Sense.

"Don't Look Now" is one of the greats.

I remember being surprised by the ending in "Hannah and her Sisters," though I know this is not a traditional twist. "Sixth Sense" was a genuine surprise. I read "Remember Me" and thought the writer did a terrific job of tension-building towards the twist ending, but then I also felt bamboozled and not entirely satisfied by it, as if the entire story hinged on a remarkably clever ending.

Others include:

"Citizen Kane"
"Black Widow"
"Dressed to Kill"
"Psycho"
"Death on the Nile"
"Se7en"
"Angel Heart"
"Chinatown"
"Casablanca"
"How to Marry a Millionaire"
"Some Like it Hot" ("Nobody's perfect.")
