[[AC:Spiders (Arachnophobia)]]
* Arachnophobia is commonly listed as the second most common phobia among humans, second only to [[PerformanceAnxiety Fear of Public Speaking]].
* Creator/SeanConnery. In the scene in ''Film/DrNo'' [[AnimalAssassin where a tarantula]] crawls on Film/JamesBond, the leg you see belongs to a stuntman, and when it crawls past his head, there is a glass plate between him and the spider.
* [[Series/CrocodileHunter Steve Irwin]], who could face down crocodiles and other dangerous animals, had this fear.
* British comedian Phill Jupitus is terrified of spiders -- and irate about people who aren't afraid of spiders and use this fact to torment him.
* Creator/StephenKing, not surprisingly, given the tendency of his {{Big Bad}}s to [[OneWingedAngel turn]] [[AuthorPhobia into]] {{Giant Spider}}s.
* According to cast interviews, Jacqueline [=McKenzie=] from ''Series/TheFortyFourHundred'' is afraid of spiders. Joel Gretsch responded with a series of [[JerkAss increasingly]] [[DudeNotFunny unfunny pranks]].
* Music/TaylorSwift. She freaked out on the way to film a scene for the "Love Story," music video because there was a spider on her dress.
* Like his best-known character, [[Franchise/HarryPotter Ron Weasley]], Rupert Grint is terrified of spiders and claimed that he couldn't even watch the scenes with the giant spiders in the Chamber of Secrets.
* Robert Fuller. His ''{{Series/Emergency}}'' castmates found lots of ways to playfully torment him with it.
* Fantasy artist Amy Brown. At least two of her paintings were created as attempts to help her get over this fear, to no avail.

[[AC: Cats (Ailurophobia)]]
* Napoleon was scared of cats. Maybe if his enemies knew that, he would have been defeated after his first battle; the caricaturists that represented him [[http://img577.imageshack.us/img577/5586/70ym.jpg riding a cat]] (supposed to be his marshal Michel Ney, a.k.a the Red Lion) obviously didn't.
** Other famous historical people who were afraid of or at least disliked cats included Caligula, Nero, Adolf Hitler, and Josef Stalin.
* It wasn't without malice that the Cheshire Cat was made into a scapegoat in Creator/TimBurton's 2010 version of ''Film/AliceInWonderland2010''; Burton ''really'' hates cats. Whether this is a phobia or not depends on who you believe.
* It's safe to say that people in the medieval age generally were afraid of cats due to the superstition they believed that cats are connected to the devil.

[[AC: Dogs (cynophobia)]]
* This is a fairly common phobia in India, Nigeria, and most countries where fewer people keep dogs as pets.
** This might partly be caused by the fact that such countries frequently have a large number of stray and feral dogs roaming about.
* UsefulNotes/GenghisKhan was afraid of dogs. (And you can't blame him; a lot of breeds of dogs in Mongolia tend to be mean.)

[[AC: Birds (ornithophobia)]]
* David Boreanaz has a phobia of chickens. It made the ''Series/{{Bones}}'' episode "The Tough Man In The Tender Chicken" rather interesting behind the scenes
* Creator/BeaArthur also had a chicken fear. ''Series/TheGoldenGirls'' scene where Rose brings home a live chicken had to be restaged to make things easier on Bea.
* Director Creator/WernerHerzog is afraid of chickens.
* During the making of ''{{Disney/Aladdin}}'' when they brought in live parrots as reference for Iago, the crew learned that Jonathan Freeman, who voices Jafar, has a fear of birds.

[[AC:Snakes (Ophidiophobia)]]
* Michael Strahan is afraid of snakes.
* ''Film/FromDuskTillDawn'' star Creator/SalmaHayek has a real fear of snakes, and had always refused to be near them. When she read the script, she knew that her phobia would prevent her from taking the part of Satanico Pandemonium, but Creator/RobertRodriguez conned her into thinking that Madonna was ready to take the part instead, so she spent two months with therapists in order to overcome this fear.
* Creator/RoosterTeeth has Geoff Ramsey, a man who's covered in tattoos but is petrified by snakes.

[[AC:Other animal phobias]]
* Read anything from the ''Franchise/CthulhuMythos'' and remember that Creator/HPLovecraft was afraid of fish. (Possibly the fact that he had an anaphylactic allergy to shellfish had something to do with it.)
* Creator/KevinSmith is reportedly deathly afraid of sharks (galeophobia). Ironically, ''Film/{{Jaws}}'' is one of his favorite movies.
* [[UsefulNotes/TheNapoleonicWars General Andoche Junot]] apparently had an irrational fear of toads, to the point that he completely freaked out at the battle of Vimeiro because he had seen one on the road (that, or he was just drunk).
* Special effects legend turned actor Tom Savini is terrified of cockroaches. When he was working on ''Film/{{Creepshow}}'', specifically the segment "They're Creeping Up on You", one of the cockroaches touched his ankle. Savini has no memory of actually crossing the room, but he ended up on the other side of it.
* "[[http://www.youtube.com/watch?v=dQRKjoAr_q8 Soldiers vs Camel Spider]]", a hilarious Youtube video where a pair of muscular, manly American soldiers are standing on their beds ([[ShirtlessScene in their underwear]]) and hunting down a spider in their room...WITH RIFLES.
** While "camel spiders" (which aren't spiders) are not actually very dangerous, there's a ''lot'' of misinformation out there about them, most of which makes them sound [[ScaryScorpions scarier than they are]]. Freaking out is predictable if you think something can literally gouge out chunks of your flesh.
* Creator/DavidAttenborough hates rats, though he hides it well on-camera; one episode of his series ''The Life of Mammals'' shows him presenting in the middle of an Indian temple devoted to rats.

[[AC:Ghosts (phasmophobia)]]
* During interviews where ''Franchise/{{Ghostbusters}}'' is the topic, Creator/RickMoranis, known for his role as Louis Tully in the movies, claims to be afraid of ghosts.
-->"Yeah, ghosts. Scare the pants off me. The polyester pants off me."

[[AC:Water (hydrophobia)]]
* {{Cats|HateWater}}.
* People used to think rabies caused this and thus named it hydrophobia. In reality it simply causes you to choke when you try to drink water. Though since it's a reflex which is incredibly painful, and can be triggered just by thinking about drinking, it's easy to see where the misconception came from.
* Creator/NatalieWood was said to have been terrified of water. [[HarsherInHindsight She died by drowning.]]
* UsefulNotes/MichaelJordan has claimed that his biggest fear is water (because he can't swim).

* Lots of people who watched the mini-series ''Literature/{{It}}'', where Creator/TimCurry plays a murderous clown, ended up developing fear of clowns. Especially if they saw it as children or teens.
** Creator/JohnnyDepp is scared of clowns too.
* Two to one odds that Creator/HeathLedger's interpretation of SelfDemonstrating/TheJoker in ''Film/TheDarkKnight'' will be the cause of a lot of clown-based nightmares.
** Any incarnation of the Joker is bound to have caused this reaction at some point or another.
* Creator/LonChaney, Sr., the "Man of a Thousand Faces" and perhaps the single most iconic horror actor from the silent film era, once made the observation that "Nobody laughs at a clown at midnight."
* [[http://en.wikipedia.org/wiki/John_Wayne_Gacy John Wayne Gacy]] certainly doesn't help make clowns any more reassuring, between his former persona as "Pogo" and his artwork.
* Creator/DanielRadcliffe has admitted to being scared of clowns.
* Voice Actor Creator/JMichaelTatum once told a story of him going to a Halloween fun park. Two clowns followed him around the park and in the end he punched one of them, opting him to get kicked out of the park.

[[AC: Flying (aviophobia) or Heights (acrophobia)]]
* Filmmaker Creator/LarsVonTrier rarely moves far from the border of his native Denmark, and has never left Europe due to an intense fear of flying. He even turned down an offer to direct for Creator/StevenSpielberg due to this.
* Creator/StanleyKubrick also had a fear of flying, and as a result, spent the last 40 years of his life in England.
* Former soccer player and now sports coach Marcelo "Bichi" Borghi is also infamous by his fear of planes. The ''very'' few times he doesn't travel by bus/train/car with his teams, he has to be sedated to the point of almost passing out when on the plane.
* Another soccer example, former Inter Milan and Arsenal striker Dennis Bergkamp; who refused to go to the 2002 World Cup (in South Korea and Japan), because it would require him to fly. He traveled by boat for international/European matches.
* Legendary UsefulNotes/AmericanFootball announcer John Madden was famous for his aviophobia. This gave him his iconic trademark - the Madden Bus.
* [[FourStarBadass General of the Air Force]] Henry "Hap" Arnold was one of the first military aviators, and would eventually rise through the ranks to become the first (and only - the 5-star ranks were discontinued after UsefulNotes/WorldWarII) General of the Air Force. He was also afraid of flying, due to being one of the first military aviators to be in a plane crash.
* There was a reason Randolph Mantooth's character John Gage did more high altitude rescues on ''{{Series/Emergency}}''. Kevin Tighe, who played Roy Desoto, is afraid of heights.
* Music/TomPetty was also afraid of heights. In the video for "Free Fallin'", when he appears to be hovering over the opening scene wearing shades, he was strapped into a crane to achieve the effect. He wasn't wearing the shades to [[CoolShades look cool,]] but to hide how terrified he was.

[[AC:Other phobias]]
* The famed director Creator/AlfredHitchcock was reported to be deathly afraid of eggs. Yeah, the guy who made ''Film/{{Psycho}}'', ''Film/TheBirds'', and ''Film/{{Vertigo}}'' was afraid of eggs.
** Hitchcock also had a lifelong fear of policemen (dating from a childhood ScareEmStraight incident), which is why so many of his protagonists end up [[ClearMyName wrongly accused]].
** Interestingly, this type of fear is acknowledged in an episode of ''Series/FullHouse''.
-->'''Joey:''' Some people are afraid of the dark. Some people are afraid of heights. Some people are afraid of eggs.\\
'''Jesse:''' Eggs?
** In a magazine from years ago, Music/HilaryDuff stating her fear (or strong disgust) of eggs.
* Creator/StephenKing is afraid of the number 13, a condition known as triskaidekaphobia.
** Composer Arnold Schönberg similarly was afraid of the number. His greatest fear was reportedly dying on an age whose digits added up or multiplied to 13. [[{{Irony}} Which he did]], at age 76 (7+6=13) on Friday the 13th - perhaps ''because'' he feared it that much.
** French composer Jules Massenet shared their fear as well. Made weirder and arguably funnier by how the letters in his name are... thirteen.
** In fact, triskaidekaphobia is so common that many multi-story buildings skip the thirteenth floor entirely, going straight from twelve to fourteen.
* Creator/PamelaAnderson probably has the above beaten. She is reportedly a sufferer of eisoptrophobia -- in other words, she is freaked out by ''her own reflection''.
** [[UncannyValley She]] ''[[UncannyValley is]]'' [[UncannyValley a former model; can you blame her?]]
* The British Radio 1 DJ Fearne Cotton is terrified of sponges. As in, the porous things you wash with.
** Germophobic people may also fear sponges - the kitchen sponge is likely one of the most germ-infesting items in any given household.
** It could also be related to [[http://en.m.wikipedia.org/wiki/Trypophobia trypophobia, which is the fear of small or "irregularly spaced" holes.]]
* [[EveryoneHatesMathematics Mathemaphobia, the fear of math]].
