Hazbin Hotel Wiki

Helluva Boss is an American comedy/musical adult animated webseries and spin-off show of the Hazbin Hotel franchise. The series takes place within the same universe as Hazbin Hotel, but features a new cast of characters, a new tone, and a new story.

The pilot was released on November 25, 2019 on Vivziepop’s Official YouTube Channel.

  • Unlike Hazbin Hotel, Helluva Boss is recorded under SAG-AFTRA, allowing more Hollywood voice actors to be cast for the short. The casting for the pilot was done by Kellen Goff who frequently visited animator Ashley Nichols' animation streams.[15] The pilot's recording sessions were done in ensemble at SPG Studios in Los Angeles[16] while the series' recording sessions were done both remotely and at Horseless Cowboy in Hollywood, whom were also in charge of casting for the series.[17] Voice direction was done by Rick Zieff and Vivienne Medrano in the pilot, then by Medrano and Richard Horvitz in the series.
    • Alongside some of the recurring Hazbin voice alumni, many actors whom worked with writer Brandon Rogers on his YouTube channel such as Su Jan Chase, as well as actors whom worked in Broadway shows also contributed voices for the series.
  • According to Vivziepop in HAZBIN HOTEL Animation Cleanup Pt. 6 Ft. Edward Bosco, Michael Kovach, and Vivziepop, she'd be open for Richard Horvitz to voice in Hazbin, but was discouraged by it since Horvitz is SAG, which was not used in Hazbin. This was later foreshadowed for Helluva Boss as Horvitz was acquired to voice Moxxie in the short.
  • Although Helluva Boss still utilizes selective Hazbin animation talent, it also uses several animators who worked on Villainous, a Cartoon Network Latin America original series, most of whom became a part of the project after leaving the series due to controversial reasons. Villainous and Hazbin Hotel are often compared to one another by fans.[18]
    • Alan Ituriel, creator of Villainous, is also aware of Hazbin but refuses to do any drawing requests featuring characters from the series due to copyright reasons with the exception of the FAN SERVICE stream due to the more loose rules of that stream.[19]
  • Although the show is set in the same universe as Hazbin, open connections between both shows are kept at a minimum due to legal concerns as Hazbin was being pitched through networks at the time before the series was acquired by A24, and Vivziepop intended for the show to be more of a standalone independent web series as the comedy nature of the show is far different compared to the comedy-drama nature of Hazbin.[citation needed]
  • Brandon Rogers, who co-wrote and voices in the show, is also known for his Mad Tea Party video on his channel. Coincidentally, a fan of Hazbin made an animatic with selective bits from said audio and Vivienne herself commented on it; which may have been an influence for Rogers' involvement in the project.[20]
  • According to Vivziepop, Helluva Boss is more episodic in nature.[16]
  • According to Vivziepop, Helluva Boss was produced faster than Hazbin Hotel as she gained enough experience producing Hazbin Hotel to not only assemble a new crew but also make decisions that made production more effective.[21]
  • According to Vivziepop, the demon that made a slight cameo in the "Inside of Every Demon is a Rainbow" music video is indeed Blitzo, whose final design was still being worked on when his cameo spot on the video was being worked on.[22]
  • According to RebelTaxi, who initially applied for storyboard work on the pilot, all tests for the show require artists to interpret excerpts from Brandon Rogers' work in order to be inquired.[23]
  • While Brandon and Richard were personally acquired by Vivziepop and casting director Kellen Goff, Erica Lindbeck and Brock Baker auditioned for their roles.[24]
  • Jayden Libran previously worked with Vivziepop and Maxwell Atoms as a puppeteer on Atoms' shelved series Dead Meat.
  • Although Vivziepop stated that recording for episodes had been delayed due to the recent COVID pandemic,[25] voice actor Jayden Libran has confirmed that recording officially continued through individual, in-studio sessions, as opposed to group recordings.[26]
  • Eight episodes of Helluva Boss are in production thus far.[17]
  • Jefferson Friedman, Matt Novak and Christopher French, composers whom are known for their work on DC's Harley Quinn, one of Medrano's favorite shows, also score for the series.
  • According to Vivziepop, Brandon and herself initially wrote the episodes simultaneously by meeting once a week during lunch.[27]
  • According to Vivziepop, the songs performed in Helluva are more non-diegetic in contrast with Hazbin Hotel's diegetic musical nature, as Helluva is more comedic and wasn't really intended to have musical songs. This is why most of the songs in the series' are either advertising jingles or performed by characters on a venue of sorts.[28]
