I don't remember there being a point where they actually mentioned it.

I think his actual name is Dutch Angle.

They definitely mention "Goodboy" in the movie as I was under the impression that was his last name. Between the hero being named "Goodboy" and the villains being named "Psychlos", it's hard to believe an adult wrote this shit.

J.R.R called his evil mountain , Mt. Doom.

Sometimes authours like to be on the nose.

Sometimes authors are overrated.

J.R.R. pretty much invented the fantasy conventions we take for granted. He can be forgiven for pointy hats and ominous sounding geology.

Hubbard on the other hand, is a hack who needed to invent a religion to sell his books.

The aliens are what people will become unless they clean out their thetans. The normal humans are scientologists.

Battlefield Earth was originally a book written by the founder of Scientology, L Ron Hubbard. Like a every group of crazy people, Scientologists have created a massive hero cult out of their former leaders, so they like to pretend he was some great author when really he was just a mediocre pulp novelist.

Scientologists don't actually say Battlefield Earth is true story like they do for a lot of the sci-fi shlock Hubbard wrote, but they do say it's supposed to be an important metaphor for the evils of modern psychiatry, or something.

The book is considered to be an accessible way to explain some of the principles of Scientology to people outside of the church, sort of like Objectivists recommending Atlas Shrugged to people (only none of Rand's Objectivist novels are remotely "accessible").

Hubbard claimed the book had nothing to do with Scientology and he wrote it just for fun (it was intended as a throwback/homage to his days as a poor pulp-fiction writer), but that's not entirely true. Basically, the novel goes out of its way to make sure you, the reader, realize that the aliens, the Psychlos, are essentially only good at making war and dominating things poorly because their society is built on technology and science and reason and logic and no spirituality. They're basically just all E.T. bureaucrats with no souls and lots of firepower. Humans are turned into some kind of noble savage archetype and because of their innate humanity, are superior to the Psychlos.

Actually, I'm probably describing the book more eloquently than Hubbard could actually ever write, because the guy was a terrible hack. The only reason his pulps are coming back into print now is because of the CoS. He was clever, though...he managed to dupe people into a cult of personality similar to Rand, but knew how to orchestrate it solely to vacuum money from people's wallets in ways that would embarrass Rand.

Oh, and one more thing:
I love how this movie has so many weird spots where it slows way down and forces you to meditate on it for way longer than is necessary. The part in this clip where it slows and Travolta is all "DO YOU UNDERSTAND ME?" happens in all sorts of places in this movie in different contexts...the pacing is one of the most bizarre things I've ever seen in a big Hollywood movie.

He also fired on mexico.

Those moments are intended to foster cognition in the PC by providing an opportunity to clear any MUs that might have enturbulated the commline.
