After Entertainment Weekly’s breaking news of Invader Zim returning as a TV movie, some fans were skeptical. Adding to the skepticism was show creator Jhonen Vasquez initially posting on Twitter that it wasn’t true. But then Nickelodeon released a teaser clip featuring returning voices Richard Horvitz (Zim) and Rikki Simons (Gir) and Vasquez confirmed he’d actually been working on TV movie for a year. The return date has not yet been announced.

UPDATE: Nickelodeon has since launched two more audio teasers of Zim trying to prepare for his return.
