George Lucas gave Mel Brooks his blessing to release his 'Star Wars' parody 'Spaceballs,' though he had one condition: 'Spaceballs' could not sell merchandise.

An original review of the 1987 parody 'Spaceballs'

On June 24, 1987, Mel Brooks launched "Spaceballs" in theaters—a comedy starring Bill Pullman, John Candy, and Rick Moranis that spoofed the "Star Wars" trilogy and sci-fi tropes in general. The movie has remained a cult classic ever since. Read the Hollywood Reporter's original review of the film here.

'American Graffiti' gave George Lucas the credibility to have 'Star Wars' produced

The idea for "Star Wars" was initially rejected by studios. It wasn't until "American Graffiti," Lucas' 1973 nostalgic comedy, became an unexpected hit that anyone was willing to produce what Lucas called his "space film."

Lucasfilm discouraged fan fiction that sexualized its characters

The self-published fan fiction zines of the '60s, '70s, and '80s were obscure enough that they rarely attracted the attention of the copyright holders of their source material. But Lucasfilm, the production company behind the "Star Wars" films, threatened legal action against fans who published X-rated stories and "homosexual expressions of love" featuring its characters.

How 'Star Wars' turned toys into collectibles

George Lucas licensed the "Star Wars" franchise to Kenner Products, which created small figurines that became wildly popular. By the 1977 Christmas season, they were facing a shortage and sold mail-in rainchecks, effectively allowing customers to purchase figures that weren't yet produced. The strategy worked, portraying the toys as valuable collectibles whose price would appreciate.

'The Empire Strikes Back' was influenced by Francis Ford Coppola's 'Apocalypse Now,' a movie George Lucas was originally supposed to direct.

How American politics influenced 'Star Wars'

George Lucas believed that myths were how societies communicated notions of good and evil, and that modern myths were found on movie screens. This deep dive from the Los Angeles Review of Books explores how Lucas' disillusionment with the Vietnam War and his disgust with President Richard Nixon informed some of the themes in "Star Wars."

The original 'Star Wars' was quietly showcased at Comic‑Con in 1976 to little fanfare

In a bold pre‑release move on July 22, 1976, Lucasfilm set up an eight-foot booth and slideshow at San Diego Comic‑Con, introducing the then‑titled "The Star Wars"—with no premiere buzz, just intrigue among a few hundred early fans.

A deep dive into the long road to making 'Star Wars'

In this podcast, Chris Taylor, author of "How 'Star Wars' Conquered the Universe," details the long road—lined with studio rejections, a dismissive crew, glacially slow special effects, and last-minute edits—George Lucas traveled to see "Star Wars" through to its release.

Check out a list of some of the best Mel Brooks films, from 'The Producers' and 'History of the World' to 'Spaceballs' and 'Robin Hood: Men in Tights.'

Legendary director Brian De Palma hated his first viewing of 'Star Wars'

The "Carrie" and "Mission: Impossible" director was invited by his friend George Lucas to watch an early cut of the first "Star Wars," a draft that lacked many of the special effects that would be added later. De Palma was highly critical, telling Lucas that "The Force" was an awful name for the spiritual power Luke Skywalker eventually comes to embrace.

Watch the 'Star Wars Holiday Special,' a 1978 spin-off that became a cult classic

The CBS television special is a hokey variety show that was widely panned after it aired and, as a result, was never officially released on home video. George Lucas had little involvement, though it did feature the original cast alongside guest stars like Bea Arthur. Interestingly, it also features Boba Fett's first appearance.

A novelization of 'Star Wars' preceded the movie–and was a massive success

The book "Star Wars: From the Adventures of Luke Skywalker" was released in November 1976, six months before the film it was based on hit theaters. By February, the novel had sold out of its initial print run of 125,000 copies and would quickly sell over 3.5 million copies.

Mel Brooks served as an uncredited producer on David Lynch's film 'The Elephant Man' because he didn't want people to assume it was a lighthearted comedy.

Listen to the 'Star Wars' disco album

The 1977 film inspired disco producer Meco to record danceable covers of sections of John Williams' score. The lead single from "Star Wars and Other Galactic Funk" eventually topped the Billboard Hot 100 chart for two consecutive weeks.

The 'Star Wars' series begins where George Lucas believed the story was most accessible

The director originally conceived 'Star Wars' as a single long story, but recognized it was far too big for a single movie, so he split each act into its own film. He began with the fourth act, which would later be renamed "A New Hope."

Jim Henson's 1986 film 'Labyrinth' was initially a commercial failure in the US, though it slowly gained an audience that now considers it a cult classic.

George Lucas used Joseph Campbell's 'hero's journey,' a narrative structure that encompasses the common characteristics of multiple cultures' mythologies, to revise 'Star Wars.'

How 'Star Wars' changed science fiction

The popularity of "Star Wars" shifted the market away from the more literary, and sometimes cynical, science fiction of the 1960s and '70s. In the wake of George Lucas' space opera, publishers and studios wanted similarly optimistic adventure stories. In time, though, writers like William Gibson would react against that and, in turn, create the "cyber punk" subgenre.

Comedian Nathan Fielder opened a store called 'Dumb Starbucks,' which was protected by US parody law.

The Beatles tried to get the rights to make a 'Lord of the Rings' film starring the band members as Gollum, Frodo, Gandalf, and Samwise.

Read a 1971 magazine feature on Lucas' debut film, the sci-fi 'THX 1138'

Almost a decade before the arrival of "Star Wars," George Lucas directed "THX 1138," a grim science fiction film about a dystopian future in the vein of George Orwell's "1984." This article from the October 1971 issue of American Cinematographer features a young George Lucas, who developed the film from a short he worked on while a student at the University of Southern California just a few years earlier.

Why many critics and fans hated 'The Phantom Menace'

The 1999 film, and the first piece of the larger Skywalker storyline, was supposed to be a grand event. It did well commercially, but it was mocked by critics and fans, who felt the story, dialogue, and the off-putting comic relief of Jar Jar Binks were a disgrace to the franchise. This NPR retrospective unpacks that reaction, and how much has changed in the decades since.

The numbers behind the 'Star Wars' franchise

The "Star Wars" movies include some of the biggest blockbusters in Hollywood history, with the original film, 1977's "A New Hope," earning a 2,400% profit. Only one of the franchise's movies (2018's "Solo") has lost money at the box office.

Steven Spielberg and George Lucas are noted fans of Norman Rockwell

The famous film directors are admirers and collectors of the American painter. Lucas, in particular, relates to Rockwell’s process, which resembles casting for a film. In 2010, the Smithsonian American Art Museum introduced a Rockwell exhibit showcasing works from Lucas’ and Spielberg’s private collections. This video from that exhibit features both directors talking about how and why they became interested in acquiring Rockwell’s work.

Why mythologist Joseph Campbell loved 'Star Wars'

Joseph Campbell, the literature professor who wrote about the power of mythology, suggested that "Star Wars" was a powerful modern myth that used classic archetypes to communicate a universal message.

Mel Brooks wanted Richard Pryor, then a relatively fresh stand-up comic, to star in 1974's 'Blazing Saddles,' but Warner Bros worried that he was not reliable enough for a leading role.

Mel Brooks got his start in comedy by accidentally flubbing a scene in a play and turning it into a fourth-wall-breaking joke, something that would later become a hallmark of his humor.

'SNL' spinoffs have had mixed success

As “SNL” became more popular, Lorne Michaels sensed an opportunity to turn some of the show’s most popular sketches and characters into feature films. It’s a strategy that had mixed results: “Wayne’s World” and “The Blues Brothers” are modern classics, while others, like “It’s Pat” and “The Ladies Man,” performed poorly with audiences and critics alike.

Mel Brooks got his first big break in 1950 as a writer on Sid Caesar's 'Your Show of Shows,' a pioneering TV variety show.

Disney initially pushed Pixar to make 'Toy Story' an edgy comedy that could appeal to adults.

Lorne Michaels jokingly offered the Beatles $3K to reunite on 'Saturday Night Live,' which John Lennon and Paul McCartney briefly considered.

The 'Movie Brats'—the nickname given to 1970s film directors like Steven Spielberg, Francis Ford Coppola, George Lucas, and others—ushered in a new era of Hollywood.

The cartoonist behind 'Calvin and Hobbes' refused to license his characters, leading bootleggers to create and sell their own merchandise.

Breaking down the many box office records 'Star Wars' has broken

The first "Star Wars" film made history in 1977 when it surpassed "Jaws," considered the first Hollywood blockbuster, for the highest-grossing movie of all time. But that's just the first in a long line of records that the franchise has broken in the decades since then, with impressive records set by films like "The Force Awakens," "Revenge of the Sith," and "The Last Jedi."

Brooks' Broadway adaptation of 'The Producers' was a massive hit when it debuted in 2001, and broke a record for most Tony wins.

Before he appeared in a 'Star Wars' movie, character Boba Fett made his first public appearance at a sweltering small-town parade.

'The Big Lebowski' slowly spawned a cult following—and a religion

When it was released in 1998, the Coen brothers' film didn't garner overwhelming critical praise or generate impressive ticket sales. Over time, though, it's become one of the defining cult movies, with midnight showings where audience members dress as Jeff Bridges' "Dude" and drink White Russians. It's even spawned its own religion: dudeism.

Rockwell's 'Saying Grace' sold for $46M in 2013

The 1951 painting is classic Rockwell: an image designed for the cover of the Saturday Evening Post featuring a humble American family engaging in a traditional value. To date, it's the highest-grossing work in Rockwell's catalog. Its buyer? "Star Wars" director George Lucas.

1993's 'Super Mario Bros.,' the first live-action feature film based on a video game, was a massive commercial flop.

Jim Henson and his Muppets were part of the first season of 'Saturday Night Live' because NBC was hoping to tamp down Lorne Michaels' countercultural plans for the show.

A bootleg video of a 1966 conversation between Bob Dylan and John Lennon has long been a cryptic text for the artists' superfans.

B-movie king Roger Corman mentored many of the star directors of 1970s Hollywood, including Francis Ford Coppola, Martin Scorsese, and Ron Howard.

In 1980, Steven Spielberg added a scene depicting the interior of an alien spaceship to a rerelease of 'Close Encounters of the Third Kind' at the studio's request, but later regretted the decision, believing it depleted the movie's enchanting mystery.

Pixar's earliest days began with a handful of academics developing the technologies they thought might make fully animated movies possible.

The Lucasian Chair is among the most prestigious academic positions in science

Once held by icons like Newton, Dirac, and Hawking, the position was founded in 1663. "Star Trek" imagined the Lucasian Chair’s future holder as the android Data, cementing its mythos across scientific and science fiction realms.

Many critically panned cult classics did well at the box office

Franchise flops like 1997's "Batman & Robin," 1983's "Jaws 3-D," and 2015's "Fantastic Four" were panned, though that didn't stop them from selling hundreds of millions of dollars in tickets.

Mel Brooks became an EGOT winner in 2001, meaning he's been awarded an Emmy, a Grammy, an Oscar, and a Tony.

Many believe modern fan fiction began with 'Star Trek.'
