The Great Indoors star Joel McHale and Modern Family‘s Sarah Hyland have signed on to the cast of Dimension 404, Hulu’s six-episode sci-fi/fantasy anthology scripted series from RocketJump and Lionsgate. They join previously announced Lea Michele, Robert Buckley and Ryan Lee.

Inspired by the Internet’s “404” error code, Dimension 404 aims to evoke that 3 AM feeling of wandering onto the weird side of the web, stumbling upon stories that cannot be explained in the world that we know.

McHale will appear alongside Michele and Buckley in a separate episode as Mr. Maker, a charismatic, eccentric yet slightly patronizing founder of a matchmaking company that offers single adults a seemingly perfect solution to finding love. Hyland will play the female lead in a stand-alone, hour-long episode as Chloe, an unassumingly cute, typically independent high school student just discovering that boys are into her. With her older classmates’ opinions increasingly taking on more importance, Chloe pushes her uncle/best pal, Dusty, to take her to a screening of a new sci-fi action film in a fresh, never-before-seen cinematic format – “Cinethrax” – which gives the audience a strange, perilous movie-going experience.

Dez Dolly created the series with Will Campos, and Dolly is executive producer/showrunner. Co-Creators are Dan Johnson and David Welch. Freddie Wong and Matthew Arnold are also exec producers.
