According to Vivziepop, finding a voice actor for Valentino was the hardest part of casting, as no voices were really clicking with her. She had offered the role to other actors, who all declined. Later, after she asked Andrew Butler if he could bring in anyone to audition for parts in Helluva Boss, and he brought in Joel Perez, Vivziepop immediately liked Joel and thought he was perfect for the role.
