Sador of the Malmori and his crew of mutants roam the galaxy in a huge spaceship armed with a Stellar Convertor, the most powerful weapon in the universe. When Sador claims the peaceful farming planet of Akir as a colony, young Shad volunteers to take Sapient Ship Nell and seek out mercenaries who are willing to fight him. They find Gelt (a Professional Killer who just wants to live on a planet where no-one's trying to kill him), Space Trucker Cowboy of Earth, Nanelia (a Mad Scientist's Beautiful Daughter), Saint-Exmin of the Valkyrie (a warrior woman looking to prove herself in battle), Nestor (a Hive Mind seeking new experiences) and Caymen of the Lambda Zone, who'd like to settle accounts with Sador for destroying his species. Counting Shad that makes seven. Sound familiar?
After Star Wars: A New Hope became a surprise hit, studios rushed to cash in on the public's sudden hunger for "Science Fiction" with a flood of bad Space Opera. Exploitation king Roger Corman had no intention of being left behind, but he showed more intelligence than most film executives by ripping off a good plot as well. When SFX companies presented outrageous quotes for their work, Corman took a leaf from George Lucas' book and created his own special effects (under the charge of James Cameron who got his "big break" with this film, along with producer Gale Anne Hurd, composer James Horner and screenwriter — later independent filmmaker — John Sayles). Corman being Corman, he made sure to get his money's worth by recycling the Stock Footage in countless other low-budget sci-fi movies. Horner's score was also used in other Corman productions (a case of Hilarious in Hindsight, given the composer's own recycling tendencies).
Battle Beyond the Stars provides examples of the following tropes:
- Actor Allusion / Casting Gag
- Affluent Ascetic: Gelt.
- Better to Die than Be Killed: Saint-Exmin's death. After her ship is disabled taking the Stellar Converter out of commission, she detonates her ship, taking three Malmori fighters with her.
- Bilingual Bonus: The text that appears on the screen of the Malmoris is Hebrew.
- Bittersweet Ending: Akir is saved but most of the mercenaries are killed.
- Bond Villain Stupidity: This is what ends up doing Sador in. By the end of the final battle he had already destroyed all the mercenary ships protecting Akira and disabled Nell, but his insistence on getting his hands on the last defenders is what allows Shad to blow him up.
- But Not Too Foreign: Akir was apparently founded by Hindus, as their Holy Text is the Vardaa. However, all the colonists are caucasian.
- Captain Ersatz: Gelt is essentially Lee from The Magnificent Seven Recycled In Space, with Robert Vaughn reprising his role in all but name.
- Chekhov's Gun: The Kelvin communicate through waves of heat, while Nestor are a telepathic Hive Mind. Both abilities come in useful as weapons.
- Comic-Book Adaptation: Bluewater Productions released a four-issue prequel called Battle Among The Stars.
- Contrived Coincidence: Good thing that Shad meets Cowboy, who is carrying a cargo load of several thousand laser rifles that were meant to a planet that was resisting Sador, which gets a nasty case of Stellar Converter while they were talking after Shad saved Cowboy from some space pirates. Cowboy even lampshades it as "well, I have this cargo and it's already been paid for... better give it to you and your folks, seeing that you have need for it and they don't anymore."
- Coming in Hot: Gelt's death.
- Cool Starship: Plenty of them, thanks to the work of James Cameron, who created a unique sound and appearance for each one.
- Deadpan Snarker: Nell, as she's none too impressed with her current wet-behind-the-ears pilot.
- Does This Remind You of Anything?: The hero's space ship looks remarkably like the female reproductive system, with guns for ovaries. The production crew even referred to it as "the flying uterus." It also has breasts, in case you didn't notice.
- Earth-Shattering Kaboom: Averted as the Stellar Convertor can turn your entire planet into a sun, but not blow it up. You're still dead though.
- Epic Movie: For certain definitions of "epic." While, for the rest of the world, this was a relatively low-budget Star Wars rip-off (not to mention a Magnificent Seven remake set on another planet, for New World Pictures, Roger Corman's production company, this was their Avatar. New World spent more money on this film than they had ever spent before or ever would — when adjusted for inflation — since.
- Evil Hand / Organ Autonomy / Life-or-Limb Decision: Sador finds out almost too late that a Nestor hand can be controlled by the Hive Mind even after it's been cut off and implanted onto his own arm. The surgeon is able to stop Sador from cutting his own throat by quickly chainsawing off the limb.
- Exact Words: After Gelt dies:Shad: Have somebody prepare a meal.Akirite: A meal?Shad: Full course, then bury it with him.Akirite: Bury it?Shad: That was our arrangement: A meal and a place to hide.
- Expy: George Peppard's portrayal of Space Cowboy is almost exactly the same as the way he'd play John "Hannibal" Smith on The A-Team a few years later.
- Face Death with Dignity: Saint-Exmin just smiles and says that it was a glorious fight before blowing herself (and a few Malmori fighters) up while Space Cowboy decides to spend his final seconds before crashing playing his harmonica.
- Famous Last Words: Sador's last words as his ship blows up around him are a plaintive complaint that he wanted to live forever.
- Fan Disservice: Shad can't resist trying the Dial-A-Date service on a long abandoned planet. The screen displaying a sexy alien female rises to reveal a decaying but fully functional android.
- Fan of the Past: Cowboy enjoys watching old Western movies, and partakes of 20th century food and booze. Subverted when Nestor eats one of his "hot dogs" and realises the meat is artificial.
- Feel No Pain: Inverted with Nestor's drones, who have no tolerance for pain whatsoever, ironically making Sador's attempt at torturing one very brief and unproductive.
- Galactic Conqueror: Sador and his space crew roam the galaxy in search of planets to conquer or destroy.
- Ghost Planet: Gelt is hiding on one, as he's not safe anywhere else. The only thing he wants from Shad is a place where he can have human company that doesn't want to kill him.
- Human Aliens: Yago describes the Akirans as having "forms" similar to their own: oxygen burners with bilateral symmetry. It makes sense that Sador would want to seek out victims with compatible biology, so he could use them for Human Resources if needed.
- Hand Cannon: Check out the size of Gelt's laser pistol as he re-holsters it.
- Hand-or-Object Underwear: Saint-Exmin's battle-bra resembles a pair of silver hands clutching her impressive breasts.
- Hitchhiker Heroes: The second act of the film is Shad's trip to find mercenaries.
- Hive Mind: Of the rare benevolent type. Nestor is an entire race that share the same consciousness.Nestor: You see... There is only one Nestor, one consciousness. As you might imagine, this has proven very lonely and very dull. We must avoid becoming... we believe you have a phrase for it... becoming "bored to death."
- This leading directly to why Nestor decides to have those facets of Nestor join the fight: Nestor has never fought a hopeless battle before.
- Huge Holographic Head: Sador delivering his ultimatum to Akir.
- Human Aliens: The Akira and almost all the characters who aren't Humanoid Aliens are explicitly stated to be from different species, but are all outwardly indistinguishable from regular humans.
- Insignificant Little Blue Planet: Cowboy proudly tells everyone he's from Earth but no-one has ever heard of it.
- Kick the Dog: Sador destroys a manned weather satellite orbiting Akir. After delivering his ultimatum Sador orders his snipers to gun down random citizens simply to show he means business.
- Last of His Kind: Caymen
- Loud of War: The Sonic Tank, which emits a piercing tone that makes the Akiran soldiers bleed from the ears. Fortunately the Kelvin have no ears as they communicate through waves of heat.
- Love Interest: Nanelia for Shad. Cowboy hooks up with an Akiran girl too.
- Mad Scientist: Weapons manufacturer Dr. Hephaestus, though he's senile rather than evil. He does however have a beautiful daughter.
- Magic Countdown: Averted by having Nell suffer battle damage which confuses her as to what part of the countdown she's at. She pulls herself together in the end though.
- The Magnificent Seven Samurai: One of the first films to start making this into a genuine Trope.
- Mars Needs Women: Several different takes on this — Shad finds himself being held captive by Nanelia's senile dad because he wants them to make babies. Later Caymen cheerfully admits he could sell Nanelia for a good price... but it turns out he means as food. Tembo and Kalo kidnap a bride and rape her; this backfires badly when they need to concentrate on fleeing from Gelt and she runs into the control room and starts pushing buttons at random.
- Meaningful Name: The Kelvin communicate through heat transfer. Kelvin a measurement of heat, starting at absolute zero and going up, used by physicists.
- Mix-and-Match Man: Sador seeks immortality via Serial Prostheses.Kalo: Remember Bilko? He disobeyed orders, and now Lord Sador's wearing his left foot.
- Ms. Fanservice: Saint-Exmin, played by the buxom Sybil Danning, wears some very revealing outfits, requiring glue as her nipples kept popping out. Even then the chest area had to be edited for television.
- Pardon My Klingon: Nell drops a "sorry son of a mutant" to insult Sador as one of her last lines. Which is all the more weird because she calls him a "son of a bitch" much earlier in the film.
- The Perils of Being the Best: Gelt has committed so many high profile killings and become so infamous that he's no longer welcome anywhere in the civilized galaxy. Shad finds him sitting in a luxurious throne surrounded by overflowing chests of jewels, but he's living on a Ghost Planet and Reduced to Ratburgers because there's nowhere he can risk spending his wealth. The only thing he asks for payment for his services is a square meal and a safe haven.
- Proud Warrior Race Guy: Saint-Exmin, although Shad doesn't take her seriously because she has a tiny ship, until she soundly beats them in a ship-to-ship fight. Even then, he doesn't accept that there is such a thing as a beautiful death in battle, as her race's motto proclaims, until he sees her die.Saint-Exmin: Live fast, fight well, and have a beautiful ending!
- Recycled In Space: This film is clearly based on The Magnificent Seven. Also Cowboy as a Space Trucker and Space Western cowboy.
- Reptiles Are Abhorrent: Caymen is a slaver with no interest in noble causes, or reluctance to feed captive women to carnivorous aliens. Fortunately Nanelia happens to drop Sador's name just in time.
- Self-Destruct Mechanism: Nell performs a Heroic Sacrifice to blow up the Stellar Convertor. Unfortunately her systems have been damaged so she keeps messing up the countdown.
- Sex Sells: Frustrated that no-one had built any spaceships yet, Roger Corman gave everyone a day to come up with a good design. James Cameron (then a complete unknown in the industry) was aware of Corman's reputation for sexploitation films, so drew up a design for a "spaceship with tits". Corman approved it instantly, and put Cameron in charge of building it.
- Shoot the Messenger:Yago: (carrying a small bag) Our emissary has returned from Umateal. They have replied to our ultimatum.
Sador: And? ...What's this?
Yago: It WAS our emissary, sir. That is their reply to our ultimatum. They've... powdered him!
(Sador throws the bag in a rage. A squicked Yago quickly brushes the powder off himself)
Yago: They are a proud form!
Sador: In an hour they'll be an EXTINCT one! There'll not be a trace of them left... Not even their dust.
- Shout-Out: The planet under attack is named "Akir" after Akira Kurosawa, director of Seven Samurai.
- Space People: Galt says he doesn't have a homeworld — he was born in space, which is appropriate for a cold-blooded killer, but also reflects his need for an actual home.
- Space Pirates: We're first introduced to Cowboy being attacked by jackers who are blasting his ship with laser fire to wear down the shields, whereupon they'll blast him and steal his cargo. Cowboy responds by laconically calling for help and playing a Captivity Harmonica.
- The Speechless: Caymen's minions — the Kelvin only communicate through waves of heat, and Quopeg doesn't talk either. Caymen more than makes up for their lack of dialogue.
- Standard Alien Spaceship: Nell resembles a flying uterus, and the other mercenaries' ships includes Nestor's (a glowing Flying Saucer), Space Cowboy's (which roughly resembles an overgrown Lunar Landing Module), Gelt's (which resembles a flying manta ray), and Cayman's (which has a design that makes it look like a flying mouth).
- Surrounded by Idiots:Sador: What's WRONG is that I have an army full of GENETIC MISTAKES! Why can't my minions be sophisticated or intelligent, like... well, like ME?
Yago: You can't expect all of us to measure up to YOU, Sir.
Sador: Oh, don't flatter me! Those two probably slammed their ship into an asteroid or something.
- Those Two Bad Guys: Tembo and Kalo are left behind in a fighter to keep an eye on Akir.
- Token Human: Played with. Most of the cast is made up of Human Aliens of different species, but Cowboy is the only one confirmed to actually be human, as he hails from Earth. His presence is the only thing keeping the film from slipping into A Long Time Ago, in a Galaxy Far Far Away... territory.
- Torture Technician:Sador: This is Frojo, my Third Officer. Frojo is expert at inflicting pain... while keeping the victim alive.
Nestor 2: It's good to have skills.
- Training the Peaceful Villagers: The mercenaries and Shad/Nell do all the fighting in space, but there's some ground fighting by Cowboy-trained Akirans too.
- Unusual Euphemism: Some unforgettable dialogue from Saint-Exmin on what she'd like to do to the innocent Shad.Saint-Exmin: I could do wonders for that boy! I would recharge his capacitators, stimulate his solenoid; tingle, dingle, dangle, prangle his transistors! You know: Sex!
- Utility Belt: Cowboy's belt dispenses a belt, e.g. Scotch, soda and ice. A practical man!
- Villainous Breakdown: Sador spends his final moments before his ship blows up whining that he wanted to live forever.
- Wave Motion Gun: Sador's superweapon, the Stellar Converter turns planets into stars, killing all life on the world.
- Wedding Smashers: When Tembo and Kalo become bored with their guard duty over Akir, they disrupt a wedding to steal the bride.
- Who Would Be Stupid Enough?: Sador uses this trope to deride his Number Two for Brains when asking who'd come to aid the Akirans. "No-one would be that stupid, even you!"
- Wretched Hive: Subverted when Shad lands on a planet notorious for its Hired Guns and criminal element, only to find the local planets have raised an army and cleaned it out. As Gelt puts it: "We made them nervous."
- You Owe Me: After Shad and Nell rescue him from jackers, Cowboy has no problem with dropping off his cargo of weapons on Akir (after all, his customers have just been wiped out by Sador) but Shad plays this card to make sure Cowboy stays behind to teach the locals how to use them.
