'''''Laserblast''''' is a 1978 low-budget sci-fi movie. [[MysteryScienceTheater3000 Leonard Maltin gives it two and a half stars!]]

The movie begins with two aliens landing on Earth in pursuit of a third alien. After a pathetic attempt to hide behind a bush, the third alien's pursuers unceremoniously disintegrate him and then leave. Short movie, huh?

...Well, [[YourPrincessIsInAnotherCastle not exactly]]. See, the bad guy alien was carrying a [[{{BFG}} rather large]] laser cannon with him, which the other aliens neglected to pick up (we get to see their boss flip out at them over this later). Said cannon is later found by put-down teenager Billy Duncan. Billy then starts using the cannon to gain revenge on those who wronged him. The laser cannon turns out to have an evil influence over its user, because Billy not only grows addicted to the cannon's destructive power, he also starts to undergo some kind of strange mutation. Meanwhile, the aliens have realized their mistake and are heading back to Earth to retrieve the cannon...

This was one of the first film scoring assignments of Music/JoelGoldsmith ([[JerryGoldsmith Jerry's]] son), who went on to become the musical voice of ''Series/StargateSG1'' and its spinoffs.

!!''Laserblast'' provides examples of:

* TheAllegedCar
* AmuletOfDependency: The alien amulet, which powers the cannon and slowly turns Billy into a monster.
* ArmCannon
* AttemptedRape: The two nerd-bullies do this to Kathy. Billy busts in just in time and beats them up (sort of).
* {{BFG}}: The laser cannon, which is worn around ''the entire arm''.
* {{Bizarrchitecture}}: One scene has a door with its knob placed higher than normal, while another has a window with its drapes placed lower than normal.
* ButtMonkey: Billy, when nerds pick on you, you're low on the totem pole of teenage status.
** Getting picked on by Creator/EddieDeezen is the penultimate low. Only being picked on by Toby Radloff could be worse.
** WhosLaughingNow?
* DownerEnding: [[spoiler:Billy is completely corrupted by the cannon's influence and goes on a rampage. The aliens show up, kill him and take back the cannon. The End.]]
* DudeLooksLikeALady: The laboratory technician, due to his odd haircut.
--> '''Crow:''' Goodbye, Mrs. Joe Don Baker.....
* EvenNerdsHaveStandards: Even the nerds think Billy is a loser.
* EvilWeapon: The laser cannon.
* HollywoodNerd: A quite bizarre case, as the ''bullies'' are portrayed this way, one of them even being played by consummate Hollywood Nerd actor EddieDeezen. "It's some parallel world where the nerds bully the jocks."
* HowDoIShotWeb: After he finds the gun, Billy spends several minutes dancing around with it, trying to figure out how it works.
* HumanAlien: The bad guy alien vaporized in the prologue. The other aliens may owe their appearance to Dale Russel's Dinosauroid (see the Human Alien trope page for more on him).
* TheMenInBlack: Gianni Russo's character vaguely following the trail of the alien gun, although he wears a green [[TheSeventies seventies]] casual suit instead of basic black.
* MundaneMadeAwesome: "I'm gonna drink the '''hell''' out of this Coke!"
* PoliceAreUseless: The Sheriff's Department here makes [[TheDukesOfHazzard Roscoe and Enos]] look like [[WalkerTexasRanger Walker and Trivette]].
** If the boss alien's rant is any indication, the two hunter aliens aren't much better.
* PoolScene
* ProductPlacement: The protagonist is seen drinking Coca-Cola in a few shots. Mike and the Bots theorize it was done by Pepsi to discredit Coke.
** A can of Pepsi can be seen at the pool party. An act of revenge by Coke?
* RepeatCut
* TheSeventies: ''And how''.
* ShellShockedSenior: Grandpa's never been the same since the Spanish-American War...
* TheStoner: Everyone, including the police.
* StuffBlowingUp: To the point of becoming an OverlyLongGag.
* TakeThat: Billy destroys a ''StarWars'' "billboard" with his cannon. Thanks to this movie's budget, it's not even an actual billboard -- just a sign upon which someone stenciled the ''StarWars'' logo. Yeah, this movie ''totally'' gave StarWars a run for its money.
** Oddly enough, the actor who played Billy Duncan co-starred with [[StarWars Mark Hamill]] in the film ''Corvette Summer,'' which was released the same year as ''Laserblast''.
** This may be one of the reasons why, for a brief time, people took ''Laserblast'' seriously, compared it to ''Star Wars'' and discussed which film was better and why.
* TheUnintelligible: The aliens.
* ThoseTwoGuys: When the aliens aren't shooting people they pretty much act that way.
* VillainProtagonist: Billy. Maybe.
* WalkingShirtlessScene: Billy always has his shirt open, for...some reason.
* WhatHappenedToTheMouse: Colonel Farley.
