"Darkness falls early. From the horizon comes the wail of creatures pretending to be human. The red tide has come in, and shapeless things float toward the shore. He stands before the altar of Art, naked and with fists raised, and he vows: I will not be lied to.
Hello. My name is Harlan Ellison and I am a writer."
—Introductory paragraphs of Ellison's first An Edge In My Voice column
"Demon with a Glass Hand" and "Soldier", episodes of The Outer Limits. James Cameron used them as the basis of creating The Terminator (by accident, so Jim claims), and Ellison caught him red handed and got a cash settlement and an official acknowledgment in the credits.
"'Repent, Harlequin!' Said the Ticktockman", Hugo- and Nebula-Award-winning 1965 short story. Which, he writes in an intro to the story in [not sure what anthology], that he wrote it all in one sitting, the night before he had to hand it in for a writing-workshop.
"The Beast that Shouted Love at the Heart of the World", Hugo-Award-winning 1968 short story
"A Boy and His Dog", Nebula-Award-winning 1969 short story made into Hugo-Award-winning 1974 film
Phoenix Without Ashes, a screenplay written in 1972, which became the 1973 TV series The Starlost. The series suffered so badly from Executive Meddling that he insisted on being credited only under a derisive pseudonym. ("By Cordwainer Bird" means you know it's a turd!). With Edward Bryant, it was expanded into a novel shortly after; and in 2010, the original screenplay was adapted into a comic book miniseries.
Harlan Ellison's Watching, a movie review column for the Los Angeles Free Press and The Magazine of Fantasy and Science Fiction.
The Glass Teat and The Other Glass Teat, a two-book collection of television and social criticism.
Was hired by Warner Bros. in the late 1970s to write a film adaptation of Isaac Asimov's I, Robot; the script (which is available in book format) is highly-regarded by those who have read it, but the project fell apart after Ellison accused a studio exec of having the intellectual capacity of an artichoke.
Spider Kiss (aka Rockabilly), a 1961 novel about a sociopathic teen idol and the publicist who has to keep the singer's drunken rampages out of the scandal sheets. His only full-length novel, and also the only novel given a spot in the Rock 'n Roll Hall of Fame.
Two third season episodes of The Man from U.N.C.L.E.: "The Sort of Do-it-Yourself Dreadful Affair" (Season 03, Ep. 02) and "The Pieces of Fate Affair" (Season 03, Ep. 23). The latter was, for a long time, the series' "Missing Episode", as Ellison had unwisely parodied a number of his literary acquaintances, and used several friends' names for characters, resulting in a lawsuit against Ellison and the removal of the episode from syndication packages until 1985. (Ironically, the friends themselves didn't have a problem with it!)
Things he's famously grumpy about include, but are certainly not limited to:
People who discount all science fiction as being no better than the worst of film and TV sci fi ("that hunchbacked, gimlet-eyed, slobbering village idiot of a bastardized genre").
In fact, as of Dream Corridor, he hates the label "science fiction writer", which he sees as too limited, and really doesn't like the label "sci-fi writer".
People who ask him about the jellybeans in "'Repent, Harlequin!' Said the Ticktockman".
Which were lampshaded in the story itself.
People who ask him when The Last Dangerous Visions is going to be published.
Similarities between his Outer Limits episodes and the film Terminator, which led to a lawsuit and a credit for him in subsequent releases of the movie.
The changes made to his script for "The City on the Edge of Forever" before it was filmed. It's worth remembering that his original version of the script won him one of his Writers Guild of America Awards — but on the other hand, it was the final broadcast version of the episode that won the Hugo. (It's also been suggested that his version of the episode, had it been filmed, would have murdered the budget and then been murdered in turn by Standards and Practices.)
William Shatner said he attempted to talk to Ellison during the ordeal to try and calm things down. According to Shatner, Ellison responded by yelling at him.
Apparently Paramount has taken the tactic of declaring most, if not all, elements of the story off-limits for the Expanded Universe after Ellison sued them (and the Writers Guild of America) for 25% of the royalties for every time they were used from 1967-2009. Paramount settled out of court.
Ellison's own book about the controversy includes both versions of the script. Comparing both, one is reminded of the words of J. Michael Straczynski, with whom Ellison would later work on Babylon 5; "You wait a week or two, then the writer comes in, and you expect to hear a great story about your characters... And what you get is a story about an outside character who comes in and has adventures, a story in which your regular characters are passive participants or downright irrelevant."
Star Wars, because people consider it a good science fiction story but it doesn't really examine the effect of the setting on humanity as a whole. He also feels that the film has no humanity or soul, and feels it "keeps people stupid" and ruined the public cultural perception of science fiction. It's especially evident in his infamous rant "Luke Skywalker is a Nerd and Darth Vader sucks runny eggs", collected in his book "Watching".
Wikipedia. He terms it "dangerous and hurtful crap".
Harlan Ellison isn't really grumpy all the time, and he does have friends, and there are also stories demonstrating that he's capable of being a wonderful human being. He also appeared as a grumpycaricature of himself in Scooby-Doo! Mystery Incorporated, giving a lecture that concluded "... and that's why nothing good has been written since the 1970s". The stories about Grumpy Harlan Ellison are a lot funnier, though (example: allegedly once mailing an executive roadkill — fourth class — along with a recipe for gopher stew).For an in-depth look at the man's genius, madness, and general assholery, check out the documentary on his life and career: Dreams with Sharp Teeth. The film features commentary by Robin Williams, Neil Gaiman, Ronald D. Moore and others who have known, worked with, or have been influenced by Ellison and his writings.
Cursed with Awesome: "Seeing" revolves around a woman whose mutated eyes allow her to see in ways that normal eyes (and brains) can't begin to process. She hates her vision because it's made her life miserable.
Death by Sex: Implied for humanity as a whole at the end of "How's the Night Life on Cissalda?"
Also, debateably, his whole life. As Neil Gaiman said (In Dreams with Sharp Teeth) "I think all of Harlan's work is actually a giant piece of performance art, called...Harlan Ellison."
Laugh Track: In-story in "Laugh Track". The ghosts of those whose laughter was recorded are now trapped in it, and one of them gets out and starts jeering at the awful comedies it's being used for. (An explicit comparison is made to the idea of a soul-stealing camera.)
Magical Negro: Explicitly averted in "Paladin of the Lost Hour" and "Mefisto In Onyx".
Mind Rape: Made very literal in "Broken Glass"—the antagonist is a telepathic voyeur/rapist who watches the main character's torrid fantasy and then assaults her fantasy version of herself.
Mind Screw: His latest short "How Interesting: A Tiny Man".
Unreliable Narrator: Many of his stories about his interactions with Hollywood/other writers have gotten called into question by the rest of the science fiction community. Ellison is one of those people who won't let the truth get in the way of a good story; take anything he says with a salt mine.
Why Fandom Can't Have Nice Things: Wrote an essay on it (sci fi/fantasy literature, specifically), called "Xenogenesis", which included a number of examples of the awful things that have been done to him and other writers by fans.
