A 2006 film starring Music/TenaciousD founders Kyle Gass and Creator/JackBlack, known in the story as Jables and Kage. It's a [[BigDamnMovie spin off]] of [[Series/TenaciousD a lesser known HBO series that premiered back in 1997.]] In it, the explicit details of the band's origins are explored, and a strong change in dynamic is observed ([[RandomEventsPlot from just sitting around doing random shit]] to sitting around doing random shit and going on an adventure on the big screen).

The film has two main parts to the plot. The first part deals mainly with the formation of the band. In the beginning, Jables, a young rocker living in an oppressive, religious household, prays to a poster of Music/RonnieJamesDio, and is given a vision of his future. He is bidden to [[TheRunaway run away]] from home to California, where he is to meet [[HeterosexualLifePartners his best friend]] and [[TheLancer band partner.]] [[TravelMontage After traveling far,]] he meets this man, Kage, who turns out to be something of a bum wanna-be. Kage gives him extensive rock "training."

The second part involves the two trying to create a masterpiece song to pay their rent. During a jam session, they stumble onto the secret of [[MacGuffin an ancient rock artifact known as the Pick of Destiny.]] It happens to be [[RuleOfCool Satan's tooth.]] The two then go on an adventure to retrieve said artifact, and get into all sorts of trouble along the way.

[[CultClassic The movie, like the band itself, has a strong cult following.]]

** [[spoiler: Power-slides and cock push-ups]] both turn out to be very useful tools for stealing the Pick of Destiny.
** Also, the video game Kage plays gives him the skills to escape the cops in real life during "Car Chase City".
* ChessWithDeath: [[{{Dissimile}} Not so much chess as a rock off, and not so much Death as Satan himself.]]
* ClusterFBomb:
** Whenever Jables is improvising song lyrics. Just listen to "Classico".
** Satan's initial boast and reaction definitely qualifies. See OhCrap below.
** Also in "Kickapoo":
-->''Oh the dragons balls were blazin' as I stepped into his cave, then I sliced his fuckin' cockles, with a long and shiny blade!/'Twas I who fucked the dragon, fuckaly sing-fuckaloo!/And if you try to fuck with me, then I shall fuck you too!''

* DramaticIrony: Music/MeatLoaf, as the very religious dad, punishes young Jables for liking/playing rock 'n roll in the house.

%%* EtTuBrute
* EyeScream: One of the Rock and Roll History Museum guards claims to have forced two hostiles to gouge each other's eyes out, simultaneously.
* FantasyForbiddingFather: Jables' dad tries to prevent his son from becoming a rock star, telling his son that rock and roll is a corrupting influence of Satan that brings chaos to the world. [[ProperlyParanoid He is completely right.]]
* {{Foreshadowing}}: Jables' father warned him that the rock music would make him Satan's puppet and bring chaos to the world. He would have been right if Jables and Kage hadn't defeated Satan in the rock-off.

* GroinAttack: Jack slips and falls, straddling a tree branch. "OW, SWEET BABY!" indeed.
* GroupieBrigade: Seen during Jables' dream sequence.
* GuileHero: [[spoiler: Jables, see FridgeBrilliance.]]
* HeroicFantasy: The second half of the movie, when Jables and Kage go after the Pick of Destiny, the plot basically [[GenreShift shifts]] to this. I mean, it's still set in the real world, but all the tropes are there.
* HonourBeforeReason: Turns out that even ''the Devil'' must abide by the Demon's Code and accept any declaration of a rock-off challenge. Keep in mind, he presumably wrote this part of the code in the first place.
** Also, while the Devil can't refuse the challenge, it appears that [[KangarooCourt he is the sole judge of who wins]]. Which may be a factor in why he has never lost.
* IntimateMarks: Both Jables and Rage Kage have [[BirthmarkOfDestiny Birthmarks of Destiny]] on their hind quarters that spell out "Tenac" and "ious D" respectively. They take this as a sign to name their band Music/TenaciousD.
* InvisibleBackupBand
* IronicEcho: When Jables sees a hot girl walk past Kage's apartment, Kage tells him to be on top of his sexual game because there'll be ten times hotter girls backstage when they perform. Later, when Kage is DistractedByTheSexy at the diner, Jables tells him to forget the sorority girls because there'll be ten times hotter girls backstage when they win album of the year.
* ItWasWithYouAllAlong: Parodied. When the guys break the POD before going on stage and start crying, the open mic host, [[spoiler:actually Satan in disguise]], warmly reassures them that [[MagicFeather they don't need a magic guitar pick to channel the Devil in their music]], then gives an inspiring, heartfelt speech about how Satan lives within "all of our hearts", ever tempting us to debauchery and defiance. [[FamilyUnfriendlyAesop Jables and Kage find this comforting]].
* JerkassHasAPoint: Jack's dad was oppressive & violent but he was right about a few things. [[spoiler:"Beelzlebub did pull the strings, Jack's heart did lose direction, & it did bring chaos.]]
* LargeHam: Jables, Creator/JackBlack after all. And [[Music/FooFighters Dave]] [[Music/{{Nirvana}} Grohl]] as Satan.

* LouisCypher: [[spoiler:The open mic night host.]]
* MacGuffin: The eponymous Pick of Destiny.
* ManChild: Both of them, but especially Kage.
* {{Metalhead}}
* MicDrop: JB knocks the mic stand over after the D's first "concert" (a one-song amateur/open mic night). The audience is not impressed.
* MirrorsReflectEverything: How Satan is ultimately defeated.
* MommasBoy: Kage, if his flashback and [[spoiler:living off his parents for 15 years]] is any indication.
* MortonsFork: The stakes of the rock-off end up being this for Satan. If he loses, he must go back to Hell (and also pay Tenacious D's rent). If he wins, he takes Kage back to Hell as a sex slave. ''Either way he has to go back to Hell''.
* MundaneMadeAwesome:
** "It's a sign... a legacy." *proceeds to show birthmark on ass*
** Power sliding [[spoiler: past the security guards under the security door]].
* MundaneUtility: The stipulations of Tenacious D's [[spoiler:rock-off with the Devil]] is that if they win, [[spoiler:the Devil must go back to hell]], and also has to pay their rent.
* MushroomSamba: When Jables gets lost out in the woods, he survives by eating unidentified mushrooms, which results in a trip wherein he becomes a baby sasquatch, and then begins singing about how his dad is awesome and shall protect him.
* MythologyGag: [[spoiler:The D are met by Satan and have to play a song to save their lives (and the world).]] After surviving, they are unable to remember the kickass tune they played, so they try to rewrite it from scratch. Mayhaps a "Tribute" to that song?
* NiceJobBreakingItHero: [[spoiler: Literally, breaking it: Jables and Kage fight over the pick and break it in half. It then gets picked up by the devil, and [[OhCrap the shit immediately hits the fan.]] ]]
* NoIndoorVoice:
** Jables ends up daydreaming that with the eponymous pick, his voice will become so loud he will lose any need for microphones.
** Also, Satan. All the time.
* NoSell: After Tenacious D bust out their best [[ThePowerOfRock Power of Rock]] song against Satan in their rock-off, Satan just says "You guys are fuckin' lame!" and declares himself the winner.
* NobodyHereButUsStatues: Jables and [=KG=] act as statues in the Rock and Roll History Museum to hide from a guard.
* OhCrap:
** The song that plays when Satan gets the pick:
-->'''Satan''': ''I AM COMPLEEEEEEEEETE!''\\
'''Music/TenaciousD''': Fuuuuuuuuuuu-''[[AtomicFBomb uuuuuuuuuuuuuuuuuuuuuck!]]''\\
'''Jables''': Waaaait...waaaaait! Waiiiiit, you muthafucka! We challenge you to a rock-off! Give us one chance to rock your socks off!\\
** Kage gets one early on when his mom's voicemail message exposes him as a fraud to Jables.
** Kage gets another one during Satan's RockMeAsmodeus when he reveals his collection of [[DepravedHomosexual BDSM gear]]. Watch the look on his face switch from "awesome performance" to "I'm screwed" in a split second.
** Satan gets yet ''another'' one when [[spoiler:after accidentally blowing off his own horn, he realizes that he has given Jables a way to send him back to Hell.]]
* ParentalFavoritism: ''"You disobeyed my orders son, why were you ever born?/Your brother's ten times better than you, Jesus loves him more!"''
* PlotHole:
** Pointed out in the DVD Commentary by Jack, during the training montage, Jables collects $10 worth of coins in a cup while performing on the boardwalk. How can he assume he collected ten exact bucks just by looking into the cup?
** Soon after in the same scene, Jables goes to a nearby payphone and uses 10 cents from the cup to call Kage at home, making it $9.90. Would Jables still have enough money for the dime-bag he obtains after this scene?
* RockMeAsmodeus: Parodied, especially with lines like "I'm the devil, I love metal!". Maybe played straight as well, considering that, yes, the Devil really turns out to be the greatest metal musician of all time.
* RuleOfCool: Overused in the songs to the point that it becomes [[CrossesTheLineTwice funny]] how much it's overused. Particularly in the Master Exploder dream sequence.
* RuleOfFunny
* {{Satan}}: Appears as the final boss which the titular duo have to defeat in a rock-off challenge. [[spoiler:They lose, because the Devil is really just that good.]]
-->'''Satan''': ''[[LargeHam I'M THE DEVIL!]] '''[[ChewingTheScenery I LOVE METAL!]]'''''
* SexDrugsAndRockAndRoll: During the reunion, Kage says it was supposed to be in that order. Kage goes off to a party, Jables into the forest and eats [[MushroomSamba mushrooms]], and then they both get the Pick together.
* ShockAndAwe: Satan's favoured method of attack in this movie, instead of the fire-based moves one would normally expect from him. He still seems to come from FireAndBrimstoneHell, though.
* ShoutOut: The Devil's guitar is Dimebag Darrell's famous lightning bolt Dean ML.
* SirSwearsALot: Satan, unsurprisingly. JB and KG, to a lesser extent.
* SlasherSmile: Jack Black shows his off a few times, revealing that it looks like a cross between the Joker and the Grinch.
* SmallNameBigEgo: In "History", the guys boast about being a godlike rock band that has performed all sorts of outrageous feats. The audience reaction is lukewarm at best.
* StonerFlick: The audience is now baked.
* StonersAreFunny: The movie has several gags revolving around drug use. The funniest is probably Jables' mushroom-induced hallucination.
* TarotMotifs: The opening sequence is based around them.
* TheQuest
* ThePowerOfRock: Obviously. Taken to ridiculous extremes in "Master Exploder" and "Beelzeboss (The Final Showdown)".
* UnDuet: KG ends up performing one of Tenacious D's songs to find he only remembers his lines, which are mostly just for backing.
* TheUnfavorite: Jables (see ParentalFavoritism).
* UnnecessaryCombatRoll: Jables does some while breaking into the Rock and Roll History Museum, and yet the camera continues to see him ([[TheGuardsMustBeCrazy and only the camera]]).
* WellDoneSonGuy: Jables shows signs of being this.
* WhenYouSnatchThePebble: "When you snatch the remote control out of my hand, you will have earned the right to change the channel."
* WowingCthulhu: Subverted. After the D put forth their best effort in the rock-off, the Devil just says their song was "fuckin' lame".
* WritingAroundTrademarks: [[UsefulNotes/RockAndRollHallOfFame The Rock and Roll History Museum]].
* YourHeadASplode: In the "Master Exploder" ImagineSpot, Jables causes a man's brain to fly out by singing [[ThePowerOfRock epically]].
--> Jables: "I did not mean . . ."
--> Kage: ''(He did not mean)''
--> Jables: "To blow your mind!"
--> Kage: ''(To blow your mind!)''
--> Jables: "But that shit happened to me . . . ''all the tiii-yiii-hiiiime!''"
* YouHaveGotToBeKiddingMe: Satan's reaction when Jables challenges him to a Rock Off, knowing he can't refuse it.
