It was 'exactly how we worked on Everything Everywhere, to be honest,' Kwan told Rolling Stone. The duo shot Black and Gass running in front of a green screen, assuring them it would look cool, then invited a bunch of VFX artist friends over to throw around ideas. The director said he and Scheinert were 'really intrigued by making something that falls apart on purpose,' but 'the challenge was doing it in a way where the audience was in on the joke.' The resulting 'Fenix' video is meant to look like it's gone horribly awry, but on purpose. The Daniels told Rolling Stone earlier this year that they were incredibly nervous to meet Tenacious D, but the first time they met Black on set, he simply shook their hands, farted and greeted them with a 'Hi, guys.' 'I couldn't even laugh because my brain broke,' Kwan admitted.
