"I have never forgiven that girl in Atonement, and I never will. Her motivations were so dumb, and she ruined everything."

"People today have no memory of a time when all visual media was black and white. My mom and her sister went to see it in the theater when it was released. She told me about the audible gasp that the entire audience let out as the Technicolor began."

"I think about that reveal at least once a week. It came so far from left field I never saw it coming."

"I have never forgiven that girl, and I never will. Her motivations were so dumb, and she ruined everything."

"Great movie! I never wanna see it again!"

"I watched it in the theater when I was in high school. I was talking to someone about it in class, and they said, 'It was obvious from the beginning.' Well, not to me! The biggest 'OH SHIT!' moment was in that ending sequence when you see that the key was attached to that light. I audibly said, 'Ohhhhh SHHHHHIT!!!'"

"Jodie nails that look of dread as she realizes, after she sees the moths fluttering."

"To me, the one with Mrs. White's rambling revenge monologue (apparently improvised by Madeline Kahn) is the only true ending."

"'Now I'm gonna go home and sleep with my wife!' This is, hands down, the greatest last line in any movie."

"This has become so much a part of the cultural awareness that people don't remember what a huge reveal it was. Like mainstream magazine articles debating about whether it was true or not."

"Yeah, the ending of that movie is devastating. I actually just saw it for the first time a couple of years ago, and I somehow managed to avoid any spoilers for it beforehand."

"Even Stephen King said it was a better ending than the one he wrote."

"I wrote a film class exam paper about Memento, focusing on how much the movie implies without actually telling you. IMO, the whole movie was a master stroke."

"The kids screaming, 'We’re not dead!' was such a freaking gut punch."

"I went BANANAS in the theatre. My wife was simultaneously entertained and embarrassed as hell. 😆"

"I remember my dad saying that he saw Soylent Green in theaters before the twist was common knowledge. I already knew the twist before I saw it, but I was surprised by how good the rest of the movie was, too. Some movies are only as good as their twist, but Soylent Green is just a legitimately good dystopian sci-fi movie. Great, gritty world, and I love old man Edward G. Robinson."

"Honestly, I do believe this is Nolan’s best twist ending. The Prestige deserves more recognition."

"That one is especially crazy for me, too. When Leo first found that out, I didn't want to believe it just as much as he didn't. It's really well set up for the viewer to sympathize with him."
