Tenacious D in The Pick of Destiny

As a young man, Jables (JB) runs away from his strict, religious family and oppressive Midwestern town for Hollywood after being graced by the word of Dio on a quest to form the world's "most awesome" rock band. There, he meets acoustic guitarist Kage (KG), who is performing on the street, and begins worshiping him as a rock god. JB asks KG to teach him rock and roll, only to be refused. Later in the night, a homeless and crestfallen JB mopes on a park bench, seconds before being beaten up by mobsters. KG takes pity on JB and agrees to teach him, letting him sleep on the couch in his small apartment. KG feeds JB's fantasy by pretending to be famous with a self-named band ("The Kyle Gass Project"), exploiting him to do work such as cleaning his apartment and buying him weed, under the promise that JB can audition for his fictitious band. After JB learns KG is actually unemployed and living off his parents, the two become equal, and KG apologizes to JB by giving him a brand-new guitar. They create their own band: Tenacious D, named after matching birthmarks found on their buttocks.

Soon JB and KG learn the deepest secret of rock: all the rock legends used the same guitar pick, "the Pick of Destiny", which has 'supranatural' powers (a whole level above super). It was created by a dark wizard who'd summoned Satan for his own purposes, but was promptly attacked. A nearby blacksmith heard the commotion and distracted the demon by tossing a horseshoe at it, chipping its tooth in the process. As Satan was now "incomplete", the wizard was able to banish Satan back to Hell. To repay the blacksmith, who desired the heart of a fair maiden, the wizard fashioned the tooth into a pick that would give its holder unnatural prowess with stringed instruments. Infatuated by the prospect of becoming the next great rock star, JB immediately sets Tenacious D on a quest to steal the Pick of Destiny from the Rock & Roll History Museum. Along the way, the band briefly splits up; KG decides that sex comes first in "sex, drugs, and rock 'n' roll" after getting invited to a party by young women, while JB wants to stick to the mission at hand. They are eventually reunited after KG is kicked out of the party.

Later, after an intense chase from the museum security guards, the two manage to steal the Pick of Destiny from the rock & roll museum. Armed with this supernatural pick, they plan to use the winnings from a local bar's talent contest to pay their rent, but, before they can go on stage, they argue over who gets to use the pick first, snapping it in half accidentally. The bar's owner persuades them to go on stage and compete in the contest without the pick. The owner is revealed to be Satan in human form, who places the Pick of Destiny back on his broken tooth. Complete again, he obtains supernatural powers on earth and threatens to make Tenacious D his first victims.

To save their lives, Tenacious D challenge Satan to a rock-off, which under the terms of the "demon code" he cannot decline. The terms, suggested by JB, are that if Tenacious D win, Satan must return to hell and pay their rent, but if they lose, Satan can take KG back with him as a sex slave. After the duel, Satan deems his rock better and attempts to shoot KG with a bolt of lightning from his fingertips, but JB jumps in the way to save him, and the bolt bounces off the "JB KG" drawn logo on the base of his guitar, blowing off a piece of Satan's horn. As Satan is now incomplete once again, JB sends him back to Hell with the wizard's magical incantation.

JB and KG turn Satan's horn into the "Bong of Destiny", which the two smoke from as they write new songs together.

As actors, Jack Black and Kyle Gass had wished to make a Tenacious D film since the band's forming in 1994; archived footage of banter at an early concert records Black saying "a movie – like that would be the pinnacle".^[6]

The duo conceptualized numerous ideas for the plot, though the first actual known draft of a script was published on November 7, 2000. The script was based around many songs that would later be released on the duo's eponymous debut album that would be released the following year. There is little known about the script, other than it being based around the band playing coffee shops, Black becoming fascinated by Atlantis and Black and Gass both falling in love with a girl called Simmeon who has written books about the fictional island. They later meet Ronnie James Dio, and are sent on a road trip to Miami. This concept was later scrapped.^[7][8]

At some point prior to 2003, the band were in negotiations with British studio Working Title Films to write and distribute a Tenacious D film, but Black and Gass decided to assume creative control when they were not satisfied with the writers' ideas.^[9][10][11]

In February 2003, it was announced that the band had signed with New Line Cinema to create a Tenacious D film, with Liam Lynch as the director, and Black, Gass and Lynch writing the script and being producers on the production. There was also speculation that Red Hour Productions would produce the film, which was later confirmed.^[12] Later in 2003, Black announced the film's working title as Tenacious D in: The Pick of Destiny and that the script was about the band's search for a sacred guitar pick.^[13] Filming had been expected to take place by the end of 2003;^[14] however, it was delayed by almost a year due to Black being cast in Peter Jackson's big budget remake of King Kong.^[15] In December 2004, Black and Gass performed some songs from the upcoming soundtrack of the film whilst touring Australia, and announcing that the film would include cameos from Meat Loaf and Ronnie James Dio.^[16]

Principal photography for Tenacious D in The Pick of Destiny commenced in the spring of 2005, with the production finishing later that summer.^[17] The film held its first test screening to the press in October 2005.^[18] The film held two re-shoots in the summer of 2006 and according to Lynch, every crew member from the principal photography came back because they "had such a fun time working on set".^[19] Black also stated that the filming on this production was "the most fun I've ever had filming a movie".^[20]

Black agreed to a pay cut from his standard $12 million fee to $1 million that was then split between Black and Gass.^[1]

The soundtrack, the band's second studio album, includes vocals by Ronnie James Dio and Meat Loaf. Dave Grohl plays drums on the album, as he did on their first album, Tenacious D (2001). Grohl also contributes his vocals on "Beelzeboss (The Final Showdown)", as Satan. An edited version of the album was also released, replacing all of the profanity with made-up nonsense words.

Tenacious D in The Pick of Destiny was released by New Line Home Entertainment on February 27, 2007 on DVD. A version sold by retail chain Best Buy came with a bonus disc with exclusive footage. Wal-Mart customers received a copy of the CD More Rocktastic Music from the Film bundled with the DVD, featuring excerpts of the score by Andrew Gross and John King, as well as songs from Gass' Trainwreck.

The film was released on home video on July 26, 2008 in Japan, with a deluxe edition of the movie with a t-shirt.^[34]

Home video releases have seen it bundled with Run, Fat Boy, Run and Dumb and Dumber in a three disc set for the United States and Canada whereas for the UK there was a three disc set with Fracture and The Alibi. The Australian re-release featured the movie with Be Kind Rewind in a two disc set as well as another set with the film being bundled with Grandma's Boy.

In February 2024, Tenacious D in The Pick of Destiny was released on Blu-ray by Shout! Studios.^[35] This release includes the exclusive footage from the Best Buy bonus disc.^[36]

The band's 2012 album, Rize of the Fenix, is centred around the fictional plot of the band breaking up following the release of the film, with Gass going mentally insane as Black continued his fame in the film industry.^[37] The album also begins with the opening lyrics "When The Pick Of Destiny was released, it was a bomb".

In 2016, the band marked ten years of the film's release by using The Pick of Destiny as their backdrop at various European festival appearances.^[38]
