Beginning with the third season, Modern Family has added an extremely unsettling, CGI smile to the face of Baby Lily in the opening credit montage.
The Adult Swim show Tim and Eric Awesome Show, Great Job! uses this trope for comedic effect. Whenever pictures of children are displayed on the show, there's always something terribly wrong with their face. The funny thing is, it's possible for kids to actually look like that.
The careful use of slow-motion, freeze frame and camera zoom makes pretty much every human actor fall deep into the valley at one point or another.
In an episode of House, the patient, a painter, is doing a portrait of a man's wife. When the painting is done, her husband goes to look at it, and it is horribly distorted. The same patient later sees extremely disturbing doppelgangers of Taub and Thirteen as a result of the same vision distortion... the two actors were brilliantly cast by the creators of the show. The freaky almost-but-not-quite aspect is nailed perfectly.
While not actually eerie-looking (since he's played by a real actor) the robotic sheriff from Eureka has this effect on the townspeople, who are unnerved by him and especially by his creepily fixed smile.
Red Dwarf: Holly is generally acceptable because he/she acts just like a normal human, with a lighthearted, "chummy" way of speaking. But on the instances where he/she malfunctions and reverts to Robo Speak it can be damned creepy. "The phrase 'cargo bay doors' does not appear to be in my lexicon," for example. An episode in which it is revealed that Lister is a robot lampshades this trope, with Kryten explaining that some robots were produced that were too close to humans in appearance, which was creepy for some and so they were recalled.
Done deliberately with the Data Doctor from Back in the Red, apparently inspired by Max Headroom.
The first novelizationInfinity Welcomes Careful Drivers notes that Holograms all have the big chrome "H" on their forehead to make it more acceptable and less creepy for your dead friend to be walking around and talking to you, as it makes it more explicit that the person you're talking to is not actually the real person.
Kryten mentions that his predecessor series was a notorious commercial failure because it looked so much more human that it made humans uncomfortable, while Kryten's "novelty eraser shaped head" (as Rimmer puts it) is sufficiently far enough from human appearance to avoid the valley effect.
Doctor Who: "The Robots of Death" references the Uncanny Valley effect in the form of "Grimwade's Syndrome", (named after Peter Grimwade, a production assistant who always complained about having to do robot-themed episodes) a mental disorder whose sufferers subconsciously equate highly humanoid robots with animated corpses; the robots in that particular story looked just slightly less human than the animatronic dummies on a Disneyland ride, but the idea of being surrounded by human-sized creatures with emotionless and immobile features is unpleasant enough that the audience could easily accept it.
Autons. After they were first shown, some children would refuse to walk past a clothes shop (John Barrowman included.)
In Hugo’s arms, the Doctor hung bonelessly limp, as if he might suddenly flow to the floor in a puddle. Anji had never seen a human body sag like that; no human being had that sort of muscular-skeletal frame. For a frightened instant, she felt more kinship with the man with no limbs than she did with the Doctor.
And one even has a character feel something of the sort applies to the Doctor's human companions, who are fairly ordinary-looking 20th-century Earthlings, as said character is a member of a much more homogeneous future human society:
Their variegated pigmentation, certain small inconsistencies about their facial and bodily forms, evoked a terror in me in some quite other part than if they had been merely monsters. We do not look at a Vlopatuaran land-going octopus or a Wilikranian aerial predatiger and feel quite that fear, I fancy; it takes a man like us in most but not quite, deformed in ways we simply cannot expect, to in this particular manner fright us out our lives.
The animated episode 'Dreamland' has a crude, stiff style of CG that makes it look unfinished and creepy.
In "The Lodger", there was a very strange picture on a wall... and it didn't have anything to do with the episode. You could see a cameraman in the reflection on it, though.
The gangers definitely fall into this, especially when they melt... like the fake Melody Pond baby does.
The episode never goes there, but "The Doctor's Wife" does feature the sentient consciousness of the TARDIS inhabiting what is, literally, a corpse.
The original design for the Cybermen is this, with the mouths that would open and then make no further movements as the monotone voices droned on...the empty eyehole sockets contribute to this as well. The freakiest thing about them might be that their hands are still human. *shudder*
"These were robots in human form with distorted faces, and they gave my daughter nightmares. When I asked her why she was frightened of the Cybermen but not of the Daleks, she replied that the Cybermen looked like terrible human beings, whereas the Daleks were just Daleks."
For an example that's just a few steps down from the human side, the alien-ness of the Doctor is normally expressed by casting actors who aren't ugly, but have faces or mannerisms that look... just ever so slightly strange. From the Fourth Doctor's unusually-proportioned body and bulging Creepy Blue Eyes, to the Fifth Doctor's stiff and awkward smiles that never touch the upper half of his otherwise pleasant face, the odd tempo of the Sixth Doctor's speech and motions, the Ninth Doctor's unusual bone structure, the goggle-eyed almost-handsomeness of the Tenth, the Eleventh's face that flickers between gorgeous and ugly within the same second...
Jack Harkness evokes this for the Doctor as a living fixed point in time, "a fact", which his Time Lord instincts balk at.
Invoked with Susan's dancing to Pop music in "An Unearthly Child". It doesn't resemble any dance anyone would ever do to that kind of music and looks pretty, but freaky.
The George Lopez Show, of all shows has this in George's childhood flashbacks, which take the head of adult George and paste it onto his childhood body.
Naturally, it's because they actually "integrated" the head onto child George's body, rather than doing a cheap photoshop AFV-style.
Parodied brilliantly on the live action show 30 Rock as the reason why it is impossible to do a porn video game... and then the game Tracy made went on to make $300 million. He apparently figured out a way to avoid the valley after all.
Torquemada Software's Video Strip Poker avoids this trope by using actual video clips of actresses.
The abundance of nudity mods for popular PC video games seems to indicate that people aren't so creeped out by that as they should be.
And of course, this explanation in a way even Tracy Jordan can understand:
The miniseries adaptation of Arthur Conan Doyle's The Lost World (the one starring Bob Hoskins) subtly uses this one to make the Australopithacines distinctly creepy.
LazyTown. Specifically some of the human characters and their prosthetics. Not to mention that Robbie Rotten looks just a little too close to Bruce Campbell.
The three creepiest characters on Buffy the Vampire Slayer are generally considered to be the Gnarl, The Gentlemen and Sid. The first two by virtue of exaggerated and odd movement, and the last due to being a self-animating ventriloquist's dummy. A good one.
The "lead" Gentleman, played by Doug Jones, famous for the equally creepy performance as "The Pale Man" (also known as 'the creepy guy with eyes on his hands') in Pan's Labyrinth as well as the faun. Also the creepy "Angel of Death" (also known as 'the creepy guy with eyes on his wings'. is there a pattern here?) and much less creepy Abe Sapien from the Hellboy movies. As a trained mime and body artist he clearly excels at placing himself smack in the middle of the Uncanny Valley.
Perhaps even more notable to Buffy fans is that actor Camden Toy portrayed both the Gentlemen and the Gnarl, as well as the Übervamps let loose by the First in Season 7, and the Prince of Lies in an episode of Angel. Other notable roles include Creepy Guy, Red (described in the casting announcement only as "tall" and "evil"), and Fresh Dead/Dead Raoul. Not that he's experiencing any Type Casting.
What about April the Robot from I Was Made To Love You? She's an in-universe example, as the main characters all slowly realize there is something wrong with the super-cheery way she talks, the way the she walks, and eventually her huge amounts of strength.
However it doesn't completely qualify as Max is played by a live actor (although at the time, this fact was underplayed in the media as a fiction that Max was an actual CG construct was maintained for a while, though this was dropped once the TV series started and the actor started to become known on his own merits).
Human form replicators definitely qualify. They look perfectly human, and even come off as human for the first thirty seconds they appear in the series. But soon it becomes pretty clear that there's something off. Fifth comes off as much more human and is (originally at least) a sympathetic character as a result.
A very good example is FRAN, the replicator created by Rodney McKay in Stargate Atlantis. She acts perfectly human, friendly, yet is willing to completely obey orders (meaning suicide) and is even slightly enthusiastic about it. It is very much the Uncanny Valley. The notable thing is that she is actually unsettling to the other characters (such as McKay himself) because of this, too.
Another Atlantis example is the first few appearances of the Wraith. In an attempt to avert Rubber-Forehead Aliens, their eyes and mouths were noticeably slightly too big (apparently with CGI), leading powerfully to this effect. It was apparently too creepy, or else just too expensive, and they abandoned it later on.
Mr. Data, the android in Star Trek: The Next Generation, sometimes slips a little ways down the right side of the Valley — though, as he's played by a person, he never gets very far down. Though the grimace-lockjaw-rictus-smile he had during the dancing scene in "Data's Day" greased the slope quite effectively. This trope was cited in all but name when it was revealed to Data that he was designed to not perfectly mimic humans as it tended to creep people out.
Switching him off also had this effect, though for the opposite reason (the character we were expected to believe was a machine looked disturbingly human when he was deactivated and effectively, dead.)
Of course, since Data spent so much time out of the Valley, the scene makes the audience sympathise with him and make Riker look like a jerkass. Turns out he felt like one too.
Which may be a big reason why the Amargosa scene in Generations willied out a lot of people. Especially when his emotion chip overloaded and he couldn't stop laughing.
In the episode "Clues," everyone on the ship but Data is knocked unconscious after going through a wormhole. He tells them they were out for only a few seconds, but strange hints that he may be lying begin to appear. Picard gets increasingly frustrated as he — and the audience — realize just how hard it is to figure out what's going on inside Data's head, and how unsettling that can be.
In Star Trek: Deep Space Nine, Odo's face slips into uncanny valley. As a Changeling shapeshifter, Odo normally takes the form of a humanoid man, but he has difficulty mimicking humanoid facial details. The result is that his face has very blunted features with unrealistically smooth skin. Fortunately, he does not seem to trigger an uncanny valley response in the other characters.
In Star Trek: Voyager, one could infer this is the reason why the Emergency Medical Hologram ended up being an utter failure. It seems that Starfleet crews found it difficult to trust medical care in someone "not real" and would often forget they were a sentient, self-aware hologram, leading them to treat them as though they were not even there. They also seem to have been designed a little too lifelike for people's tastes; the EMH Mk1 was too pompous, while it's replacement, the EMH Mk2 was scathingly sarcastic, etc. As of "Life-line", the Doctor's creator reveals they were up to a Mk 4 and still running into this problem.
Similar to Data, Cameron of The Sarah Connor Chronicles sometimes slips into the Uncanny Valley, such as one scene where she perfectly repeats a deceased classmate's last words, word-for-word and inflection-for-inflection. In another, equally disturbing example, while she is being crushed between two trucks, her face is covered in cuts and burns, and her head is being sliced open, she starts talking to John in a completely normal tone of voice that shifts into frantic pleading and crying just like a normal person.
A program on the Military Channel about the Gettysburg Address features a mix of live actors, with a mostly-to-completely CGI Abraham Lincoln. The CGI Lincoln squarely falls into the Uncanny Valley.
David Lynch filmed several scenes in Twin Peaks within the Black Lodge. All the apparitions in the lodge were characters who did their scenes, all speech and movement backwards. Then the filmed result was displays in reverse, giving all the action an unsettling tone.
For Tony's stag party on Coronation Street, they all wore "Tony" masks - flat unmoving faces with little cutout eyes peering out.
For some, the Generic Man sim used to illustrate animal traits on The Most Extreme avoids this by being just slightly cartoonish, especially the goofy surprised looks whenever he gets overrun by something. In other cases, this cartoonish defiance from a normal human's appearance drives this into the deepest part of uncanny valley.
The Bionic Woman/Six Million Dollar Man featured several episodes with these lovely Fembots◊.
Though he doesn't play an alien, robot, or supernatural creature, Michael Emerson's performance of Ben Linus in Lost has a hint of Uncanny Valley, as one of his techniques he uses to achieve his magnetically compelling creepiness. He sometimes goes for a long time without blinking, then blinks very slowly at a carefully chosen moment.
"Floyd", the agent from "Department 44" in the NUMB3RS episode "Dreamland". He looked perfectly human, but his affect was rather like an android with a better-than-average speech program. The bouts of "invisible cell phone" had me looking for the spinning blue ring, and the tendency toward Stealth Hi/Bye (Amita called it "materializing"), just added to the wierd factor. You would think that an agent with such a secretive group would want to blend more.
One episode of the season 5 of Criminal Minds has for title "The Uncanny Valley. Young women are abducted and paralyzed before being transformed into living dolls, giving them a surreal look. The creepiest part is that the eyes are often shown, being the only thing that they can still move.
For those of you crazycurious, hereare◊ some pictures. Sorry, they somewhat overlap...
Though not alive (or meant to be alive), Buster from Mythbusters fame falls squarely into this category, considering all of the things Adam and Jamie have done to him to get a more "human" response out of him during tests, including giving him a "spine", "brain", and even breakable "bones" for testing injury. Special mention goes out to the "death balls" used for the Plywood Builder myth, which shatter upon a lethal impact, releasing stage blood. All used for effect, of course.
This is also the reason why a myth about fooling people with a mask was busted. Even after getting the best masks money could buy, Adam and Jamie couldn't convincingly fool anybody unless they stood very far away and didn't speak. Even complete strangers pointed out that upon closer inspection, something wasn't quite right about the faces they were looking at and they quickly deduced what was going on. Oddly enough, they apparently did fool someone: Jamie's dog.
In the Aamerican version of Big Brother, at least once a season, often a veto later in the game, producers take pictures of the contestants (it can be any of them) and then morph them together into one picture. The houseguests in the competition then have to identify which two houseguests's facial features are represented in the picture. It can sometimes actually be a bit funny, such as in 10 where the one featuring Jerry (Who was in his 70s) was morphed together with another houseguest signifcantly younger than him was described as a "Demon", or rather disturbing when you see Laura in 11's mouth look significantly bigger than the rest of the face.
One episode of Wife Swap featured a New Jersey woman as one of the wives who owned a huge and ever-growing reborn baby dolls. She is shown carrying out a daily routine of brushing their hair, changing their diapers, and carrying them around with her constantly. She even brought one of them with her to her swap family's home, and the wife of the other family was understandably freaked out when she encountered the dolls.
The first appearance of the Drakh in Babylon 5 were mouthless ghost-like creatures with glowing eyes that appeared distorted as though they were only partly in one place. They were later changed to be Rubber-Forehead Aliens with a reptilian look, and future appearances of the mouthless "soldier" caste Drakh were more rendered solid rather than distorted.
Series three of Merlin features an elderly version of Merlin, portrayed by Colin Morgan in age make-up. Eerily realistic age make-up. The effect is... unnerving.◊
The educational children's show Téléfrançais has a rather...erm...uncanny puppet character named Pilote. If you're curious, start watching around 4:45 on the first episode.
The mascot from Community falls under this trope. Having been designed to have no ethically distinguishing features, it ended up being an androgynous White Mask of Doom.
On the show River Monsters, host Jeremy Wade investigated some attacks on people in Papua New Guinea. One victim told him it felt like a person was biting him. Wade eventually catches the culprit, a fish called a pacu. Native to South America, the pacu were imported about fifteen years earlier and had seriously disrupted the ecosystem. Though related to piranhas, pacu were herbivores, and their flat teeth were normally used for crushing seeds and nuts. After being transplanted, though, they were unable to find enough of their regular diet and had expanded to meat-eating, including, apparently, humans. (They were far too small to eat a human whole, but could bite off chunks, including some... painful areas). When Wade catches a big one, he pulls back its lips to reveal the teeth, which at that size were eerily human-looking.
Space: Above and Beyond features the Silicates, robots who, based on outward appearance, are nearly indistinguishable from humans, except for three things:
All Silicates (even the Sex Bot models) have crosshairs for eyes.
The odd physical tics and the occasional st-st-stuttering of speech.
The opening theme to Here's Lucy has always freaked me out.
Walking with Cavemen's human ancestors, who are actually People in Rubber Suits. Especially Australopithecus, because they are supposed to look weird, but their human proportions make them just slightly less weird than they should.
Gerry Anderson's puppets for Thunderbirds and other shows are creepy - Peter Cook and Dudley Moore doing a live-action parody are even creepier. Or funnier.
The History Channel documentary Ancients Behaving Badly focuses on famous historical figures, forensically reconstructing their personalities (pathologies and all). Unfortunately, these segments always include a CGI rendering of the subject's face — which more often than not looks like an embalmed Gelfling that wants to dine on your tasty, tasty soul.
In the live-action The Fairly Oddparents movie, Timmy's mom and dad are this. Despite being real people, they act a bit too cartoonish.
In the Japanese comedy show Vermillion Pleasure Night, the viewers are given Cathy's House.
Rainbow, the British answer to Sesame Street, features two muppets who look perfectly alright...yet Bungle, a guy in a suit, falls right into the Uncanny Valley with his realistic movements and his unfortunate design.
The majority of Power Rangers villains were far enough away from human that this rarely applied, but any time they veered toward human-like, they hit this full-force. Take, for example, Madame Woe◊ or Lipsyncher.◊
Sliders has a Big Bad in the form of the Kromaggs. The first time they appeared, they were just sufficiently not-quite-human to make them uncomfortable to look at. Subsequent returns of the Kromaggs make them look more human.
Csi Ny has an uncomfortably zombie-like woman who's lying comatose in a hospital in the first episode "Blink".
