The movie Brick takes place in a modern high school, but sounds and plays like a 1940's/50s's Film Noir; one of the students who hangs out by himself is the know-it-all informant, and the principal is the police chief or DA threatening to rein in the hero.
In X-Men: The Last Stand, Mystique refuses to answer to Raven Darkholme (her given name) because "that's my slave name."
In X-Men: First Class: Hank McCoy says about his mutation, "You didn't ask, so I didn't tell."
In New Moon, one of the wolf pack's wives gets her face nearly clawed off because she made her wolfman angry. But she forgives him, and acts like it never happened, because that's what good women do. Unfortunate Implications abound whether or not this is meant to be taken literally (and with Stephenie Meyer's writing, who can say?)
Peter Parker's problem with, ah, "shooting blanks" in the second film.
Spider-Man and Mary Jane's first kiss in Spider-Man? You know, the one where he's hanging upside down in the rain...
Depending on the audience, the following dialog might lead to snickers.
Peter: Picking up where we left off. Mary Jane: Where was that? We never got on. You can't get off if you don't get on, Peter.
How about it in the third Spider-Man movie?
Spider-Man:(pinning Venom down) You have to take off this suit! Venom: You'd like that, wouldn't you?
A classic example is from the late 80's comedy The Couch Trip where on a radio call-in show, John Burns (Dan Aykroyd) suggests to a man trying to overcome a problem with premature ejaculation, to imagine working on his car instead. His description of taking apart a transmission... well, if the caller had had the opposite problem, it would've helped.
The opening scene has Harry exuding a white light from the tip of his wand. Under his covers. With Harry hiding the evidence when Uncle Vernon comes into his room.
Later, Harry learns the Patronus Charm which makes a pure white creature come out of his wand when he thinks of his "Happiest Memory" (Total Freudian imagery.)
Harry Potter and the Half-Blood Prince, in which Ginny notices Harry's shoelace is untied and kneels down to fix it. Since we only see the top of her head near his waist... it's not hard to see what the makers were alluding to/making fun of.
And Ron asking Harry after him and Ginny are somewhere if "they did it?" and Harry looks at him awkwardly.
In Harry Potter and the Deathly Hallows Part 1 all the Death Eaters are shocked when Voldemort demands that one of them gives him their wand (in the book they look "as if he asked them for their arm". Suuuure.) Then he takes Lucius' cane wand, and snaps off it's handle, which makes Lucius (and the male auditory) wince. And then he starts measuring up his wand against Lucius'. Are you kidding me?
Sir Ian McKellen's film version of Richard III. The setting is established right off as 30s Europe. Sure, why not? Then we come to Richard's coronation scene... and down come the long, red banners with his black-and-white emblem and fervent background chanting. Oh, right.
Star Trek VI: The Undiscovered Country is a big, honkin' allegory about the end of the Cold War. It starts off with the horrible disaster on the Klingon moon Praxis, (not in Chernobyl); which forces the Klingon Empire, (not the Soviet Union) to reach out to the Federation (not the West). Conservative hard-liners then kill (not attempt to kill) Gorkon (not Gorbachev) for his trouble. From there, it diverges a bit from actual history, but you get the picture.
Don't Be a Menace features gangsta Loc Dog receiving a package of white powder from his friend, promising him that he'll get some when it's ready. Loc then measures, tests, and puts the powder in an apparatus on the stove. Of course at the end of the scene, it's shown that he's not processing heroin but rather baking a tasty cake instead.
In one version of the Dracula movie, Jonathan cuts his finger while dining with the Count, who gets a little too... excited about this and wants to suck Jonathan's finger.
In the Coppola version, Lucy enthuses about Quincy's big "thing" - namely, his bowie knife.
In Iron Man, Tony Stark is trying to unsuit himself...
Tony: Hey! Ow, ah, ah! Jarvis: It is a tight fit, sir. Tony:(pained grunting) Jarvis: Sir, the more you struggle, the more this is going to hurt. Tony: Be gentle. This is my first time.
Tony's line when Pepper shows up immediately following the previous exchange sold the scene:
Tony: Let's face it. This is NOT the worst thing you've caught me doing.
Makes one wonder what the worst thing she caught him doing was.
According to Entertainment Weekly's review of The Jonas Brothers' 3-D concert movie, there's one part where the brothers spray foam at the audience — out of a hose, if I remember the article correctly. The reviewer only hopes that the target audience doesn't see the symbolism in this.
Confederate States of America, an Alternate History where the South won the Civil War, features several false propaganda films supposedly from the Fifties that portray those favoring the abolition of slavery as evil ("Watch out, because your neighbor could be an Abby!"). Later in the Mockumentary there's another propaganda piece that asks "Have you now, or have you ever been, a homosexual?" Both are intended to be similar to the Red Scare fear of communism.
Revenge of the Fallen: The girl who aggressively hits on Sam gets squirted in the face... just not by Sam. Of course, Sam doesn't really help the scene by yelling, "Oh my God your face! Lemme get some wetnaps for your face!"
There was a scene in City Slickers where Mitch and Phil are talking about what seems to be impotence but they're really talking about using the VCR. And they've been at it for four hours.
The song "Breakin' Out" in Shock Treatment plays over scenes of Brad escaping from the asylum. But listen to the words, and it seems to be about another kind of coming out entirely...
Hoo boy, this exchange in Commando when John convinces the villain (who looks like both a member of the village people and Freddy Mercury) to let go of his daughter and have a knife fight with him.
John: You don't want to pull the trigger. You want to put the knife in me and look me in the eye and see what's going while you turn it. That's what you want to do, right?
Bennett: (With an orgasmic expression on his face.) I can kill you John.
John: Come on, let the girl go, just between you and me, don't deprive yourself of some pleasure, come on Bennett, let's party!
Bennett: I can beat you, I don't need the girl hahah, I DON'T NEED THE GIRL! I don't need the gun John. I can beat you. I DON'T NEED NO GUN! AND I'LL KILL YOU NOW!
The fights ends with John impaling Bennett on a long hard steam pipe.
In Muppets From Space, the scene where Gonzo talks about being an alien sure sounds an awful lot like coming out of the closet...
Star Trek: First Contact. Picard's "The line is drawn here!" scene sounds like he's hell-bent on avenging his own rape especially when he uses euphemisms like "I will make them pay for what they've done!"
In Police Academy 2, gun obsessive Eugene Tackleberry loses his virginity, for which he and his equally gun obsessed girlfriend have to take their guns out of their holsters etc and put them on the floor. As they do, the lights go off, and but a moment or two later a gunshot is heard.
In Girl With A Pearl Earring the scene where Vermeer pierces Griet's ear for her as well as touching her lips is symbolic of her loosing her virginity as well as the scene where he sees her hair (its played like he saw her naked).
Rhys Ifans: So in a sense, it's almost like what crystal meth would do to an addict, where you feel all powerful and almost a sense of hubris that you can do anything, and that for Connors becomes addictive. That's why he returns to being the Lizard, and guys who are on powerful drugs want everyone else to feel the same, regardless of its social benefits. They want everyone to feel that great, because they feel great.
