A 2006 film starring Tenacious D founders Kyle Gass and Jack Black, known in the story as Jables and Kage. It's a spin off of 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 (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 Ronnie James Dio, and is given a vision of his future. He is bidden to run away from home to California, where he is to meet his best friend and band partner.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 an ancient rock artifact known as the Pick of Destiny. It happens to be Satan's tooth. The two then go on an adventure to retrieve said artifact, and get into all sorts of trouble along the way.The movie, like the band itself, has a strong cult following.
Big "NO!": Jables lets one out after realizing that the Devil has him and Kage outmatched. By the end of the rock-off, the Devil ends up having an even bigger 'no' while being sent back to Hell.
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.
Fun with Acronyms: "That's where the POD lies now." "POD?" "The Pick of Destiny!" "Oh."
Heroic Fantasy: The second half of the movie, when Jables and Kage go after the Pick of Destiny, the plot basically shifts to this. I mean, it's still set in the real world, but all the tropes are there.
Marshal Erikssen shows up in a deleted scene, mocking Cage savagely.
Idiot Ball: JB agrees to put KG up as a bet for their rock-off with the devil...despite the Devil having said that he literally CANNOT decline a rock-off challenge.
Averted: In order to send Satan back to hell from whence he came. Jables HAD to strike a deal with him of some sort. Souls are probably the only thing The Devil would substantially benefit from (thus making it a deal), and he was about to take both their souls anyway if they lost. Plus it's quite likely that Satan, being who he is, wouldn't have let an opportunity like this slide by without specifically defining a Rock-Off as having some sort of stakes involved.
No Indoor Voice: An in-story example, Jables ends up daydreaming that with the eponymous pick, his voice will become so loud he will lose any need for microphones.
Oh Crap: The song that plays when Satan gets the pick
Satan: I AM COMPLEEEEEEEEETE! Tenacious D: Fuuuuuuuuuuu-uuuuuuuuuuuuuuuuuuuuuck! Satan: YES, YOU ARE FUCKED! SHIT OUT OF LUCK! NOW I'M COMPLETE, AND MY COCK YOU WILL SUCK!
Satan gets one a few seconds later:
Jables: "Wait! Waiit, you muthafucka! We challenge you to a rock off! Give us one chance to rock your socks off!" Satan (realizing he can't decline because of the demon's code): *angrily* "FUCK! FUCK!! *dramatically* FUUUUUUUUUUUUUUUUUUUCK..."
Satan gets yet another one when after accidentally blowing off his own horn, he realizes that he has given Jables a way to send him back to Hell.
Sex, Drugs, & Rock and Roll: 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 mushrooms, and then they both get the Pick together.
Shout Out: The Devil's guitar is Dimebag Darrell's famous lightning bolt Dean ML.
Slasher Smile: Jack Black shows his off a few times, revealing that it looks like a cross between the Joker and the Grinch.
Tarot Motifs: The opening sequence is based around them.
