Prime Video has released a teaser trailer for Hazbin Hotel, featuring a snippet of its new original song "Happy Day in Hell." The full cast of the adult animated series has also been announced, and it's packed with strong singers and Broadway stars ready to hold up its reputation for addictive tunes.

Based on the popular 2019 pilot by Vivienne Medrano aka VivziePop, Hazbin Hotel follows the unexpectedly upbeat Charlie Morningstar (Erika Henningsen), princess of Hell. Unfortunately Hell is dealing with an overpopulation issue, prompting Charlie to open a hotel aimed at rehabilitating her guests. Ideally, the hotel will reform them enough that upon checking out they'll be admitted straight to Heaven. Realistically, it probably won't go so smoothly.

In addition to Henningsen, Hazbin Hotel will also feature the voices of Stephanie Beatriz, Blake Roman, Amir Talai, Keith David, Alex Brightman, Kimiko Glenn, Joel Perez, and Christian Borle.

Hazbin Hotel premieres Jan. 2024 on Prime Video.
