Theoretical physicist and futuristist Dr. Michio Kaku is a big science fiction fan, even hosting a show called "Sci Fi Science" where he would figure out how to theoretically achieve popular sci fi tropes in real life such as traveling to a parallel universe, building an artificial planet, and even building a lightsaber and destroying a Death Star among others.
Former porn star Jessica Steinhauser (better known as Asia Carrera) is a member of Mensa, a classically trained pianist who performed at Carnegie Hall as a child, builds her own computers, and plays Unreal Tournament.
Her review of one version of Photoshop was published in Maximum PC magazine. On a side note, she has discounted Sharon Stone's claim to being a member of Mensa.
Loads of porn actors and actresses are secret geeks. For example Stoya is a huge sci-fi fan and has been an IT nerd since a very early age.
This video makes it very clear that Bobbi Starr knows her video games quite well.
Alana Evans is not only a hardcore gamer, but actually hosts a show about sex and gaming on SiriusXM.
Ana Marie Cox, Daily Beast reporter and frequent guest on the Rachel Maddow show, has been known to make Firefly references on her Twitter.
She and John Hodgman also toasted each other "So Say We All" on Twitter at the end of the series Battlestar Galactica.
While we're on the subject of bloggers, at least half The Atlantic's bloggers right now are geeks, self-confessed or otherwise. The most blatant example is Ta-Nehisi Coates, who rolls with the Horde, enough to write about it for Time. Business Editor Megan McArdle is also a gamer, though to what extent is unknown (She loves Civ, at least). Chief blogger Andrew Sullivan, being English-born, is an obvious Doctor Who and Monty Python fan. Josh Green is limited to music geekery, enough to put up a fight with a music website. The rest (Ambinder, Fallows, Goldberg, and Crooks) remain uncertain (unless you count Fallows's beer fanaticism as geekery).
Many, many current high-stakes poker players got their start in Magic: The Gathering; David Williams is the most famous of those. Justified in that many of the skills used in Magic translate very well to poker.
It's not nicknamedMedieval Poker in Spain for nothing.
Former Obsidian writer Annie Carlson joined the RPG Codex forums initially for a topic about a post about a comment she made on the official forums; even after leaving the company, she is still a regular poster (apparently the forums lack of filter and her tendency to "use fuck like a comma" work with each-other).
Aside of that she also tends to cosplay as characters she voiced, as well as being aware of the Abridging genre, when she noticed there's a Madoka Abridged... she went on to provide random voices for that show and even gave an approval message, in which the creator responds happily by photoshopping her face into her character Homura.
I am Cristina Vee, and I approve of this Homura Dawg.
Bill Amend, creator of Foxtrot, has a degree in physics from Amherst and avidly plays World of Warcraft, often making accurate jokes about both. Not to mention other video games, internet memes and just about any aspect of nerd culture you can reference in a family friendly comic. Bill Amend may well be the geekiest daily weekly cartoonist out there.
The fact he did a Penny Arcade comic probably speaks for itself...
David Gaider, who wrote a lot of the script for Baldur's Gate, has written fanfiction for his own video game (including a Seinfeld crossover) and posted it on fan forums. Occasionally he'll review fics and help out with fan mod dialogue.
He's also a huge Joss Whedon fanboy, to the point that he based several characters in Dragon Age: Origins on Whedon characters (Alistair as Xander being the most obvious), and liberally sprinkled the game with Buffy Speak and subtle references to Whedon's shows.
Paul Krugman, who received the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel (it is technically not a Nobel Prize) in 2008. It is not unusual for those with a Ph.D. to be nerds but he deserves a special mention. Reasons: 1) His interest in economics began when he read Isaac Asimov's Foundation books. He wanted to, just as in the book, be one of the social scientists "who understand the true dynamics save civilization". Since psychohistory does not exist, he turned to the closest thing, economics. 2) He posted thisLOLcat on his blog upon leaving for Sweden to get his Nobel prize. 3) This video. 4) To cheer himself up he once wrote The Theory of Interstellar Trade, a paper where he outlines how trade between different star system might work. It does among other things take up how time dilation could affect economics. And he's a Buffy fan!
He also did a panel at the 2009 Worldcon with Charles Stross, of whom he is a fan. Also he wrote this with he says is the closest thing to science fiction he's wrote http://mit.edu/krugman/www/BACKWRD2.html
Shane Acker, director of the Academy Award nominated short 9 as well as the feature film based on it, appears to be a bit of an anime fan as he stated during a talked with Elijah Wood on Currrent that he liked films such as Akira and Princess Mononoke.
Judging by the voice heard in theseads for the upcoming MAGFEST...
Now if only he'll do the "Balls are inert" meme in his most Duke Nukem-ish voice possible...
Another voice actress who likes video games: Kana Ueda. She owns an Xbox 360, likes playing Halo 3, is apparently pretty skilled at it. So much that Microsoft held an event so Halo players can meet her online... and get themselves fragged by her, or frag her in a friendly match.
Rie Tanaka is a big fan of online games and she even provided voice acting in many Japanese, Korean and American online games like Final Fantasy XIV (the Mi'qotes), Cosmic Break (Icy), and, just like with Kana Ueda, she dubbed one of the voices in Modern Warfare 3 (specifically the AC-130 fire control officer).
Crispin Freeman. He's a voice actor in America 'cause of him being an anime fan of franchises like Voltron and Battle of the Planets. He considered changing his first name to Mark, one of the protagonists of BOTP. He's also a scholar on classic mythology. In addition, he also teaches potential voice actors in voice workshops too.
Joe Kucan, known to gamers as the actor who portrays Kane in Command & Conquer, noted that he is an avid fan of the games and is known to be very friendly to people who've met him. The fanbase rejoiced when it was announced that he would reprise the role for Tiberium Wars and Tiberian Twilight.
Scientists discovered a gene that causes an embryo to grow spikes like a hedgehog, so they called it a hedgehog gene. Then they discovered the protein that the gene produces, so of course they called it Sonic Hedgehog. It gets better: Another group of scientists found a potential antagonist to the protein in question, and decided to name it "Robotnikinin". And better: Sonic Hedgehog was later joined by Pikachurin, so named because it is "nimble".
Scientist found a planet that orbited around two suns. They promptly named it Tatooine.
Asteroid, once thought to have ~3% chance of hitting Earth in 2029, is named Apophis. Two of the scientists who discovered it admitted to being Stargate fans.
Stephen Hawking is a big Star Trek fan, and requested to sit in the captain's chair during his guest spot on The Next Generation. He also said of the warp core while touring the engineering set, "I'm working on that." He had a guest appearance portraying himself in a scene where Data plays poker while conversing with three great physicists on the holodeck (the others being actors portraying Isaac Newton and Albert Einstein). Making him the only person to "play" themselves in Star Trek.
Hidenori Kusaka, creator of the Pokémon Special manga, doesn't get any inside info from Game Freak to help him out on his series. Instead, he plays the games when they come out and figures out which parts he wants to incorporate into the story. Some of his author notes have him squeeing over whatever new features the games have.
The Walkers are also fans of Avatar The Last Airbender. Whilst Doug is only a recent convert to the show, his brother Rob (who co-writes The Nostalgia Critic) has been a fan for quite some time, and when asked about his opinion of the show, his response was "I'm the one who's been telling [Doug] to watch it for the past 5 years."
David Hayter, best known for being Solid Snake, is the one of the few Metal Gear Solid voice actors to have played and finished said game* Christopher Randolph (Otacon) has also played and finished it. Kim Mai Guest (Mei Ling) played it but quit around the torture sequence. He also speaks fluent Japanese, has named his only daughter Natasha after the character in the Marvel comic book Black Widow, and once stated in an anime convention that he was present because he was "a big fan of Fushigi Yuugi" (he voiced Tamahome over there).
And, of course, he wrote the script for the Watchmen film adaptation.
He also wrote the scripts for the first two X-men films, and played a security guard in the first movie.
And he's also aware of the web-series thing, particularly the Awesome Series. When he's in a con with Egoraptor, Hayter was kind enough to use his Snake-voice to say one of the lines in Metal Gear Awesome: "OhMyGodHotnessIWannaBangYou!"
Hungarian voice actor and translator Dániel Hamvas proudly admits he puts all the time spent on the net to good use by incorporating the latest slang, Leet Lingo and cuss words into his translations, or those that he supervises. His most famous and renowned "contributions" are the strikingly colorful scripts of Family Guy (where he also plays the role of Chris) and The Boondocks, and he also appears to be an all-round geek, in a good sense.
The mid-'90s staff of Disney Adventures absolutely loved showing off their nerd cred in the magazine. For the better part of the decade, it was difficult to find an issue that didn't have some kind of reference to Star Trek, The X-Files, and/or Star Wars.
The comics editors were huge outspoken fans of indie comics, and managed to put (among other things) Evan Dorkin'sKid Blastoff! and Jeff Smith's Bone into the magazine.
Gabe Newell, head of Valve Software, said in an interview once that he was a brony. The internet's reaction was exactly what one would expect.
"#BringBackToonami is not about a job. It's profoundly personal for me." Quoted from voice actor Steve Blum's Twitter account. He was as excited as any fan that it's coming back.
Voice actress Erin Fitzgerald, known for her roles in Ed, Edd n Eddy (as Nazz and May Kanker), Monster High (as Abbie, Spectra, and Cupid), and Bleach as a number of characters, is a huge video gamer. Her favorite of all time is Final Fantasy VII. She's a major otaku as well (she was just a casual fan before but got really into anime after dating an otaku), and attends numerous anime conventions, both as a fan and as a guest.
After being exposed to a gamer fanbase from his voice roles as Albert Wesker in Resident Evil, D.C. Douglas has proven time and time again through his twitter and youtube accounts that he as definitely in touch with his fans among the Resident Evil and Mass Effect (where he voices Legion) fanbases.
Stephanie Sheh: Aside from being an anime voice actor, she's very vocal about her feelings on piracy. In 2010, she mentioned that she would have loved to play Knives Chao, stating her resemblance towards Ellen Wong. She mentioned on Twitter that she's a fan of The Hunger Games trilogy and would love to read other Dystopian such as Divergent and Legend.
John J. Dick, voice of Serious Sam, posts on the Serious Zone forums under the handle "booger". Among his most famous posts were the threads in which he allowed fans to suggest lines for him, which he then read and recorded in Sam's voice.
Tomokazu Sugita. One hell of a reference machine who could practically guess whatever series or games your talking about and he will explain it in detail. We could list all the examples he's played and anime he's watched and it still wouldn't be enough.
