“Community” alum Joel McHale and “Modern Family” star Sarah Hyland have been cast in Hulu’s upcoming sci-fi anthology series “Dimension 404,” Variety has learned.

McHale will appear in one 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 appear in another 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.

They join previously announced stars Lea Michele and Robert Buckley, who will also appear in McHale’s episode as a couple brought together by his matchmaking service. Ryan Lee will star in another episode as Andrew, a teenage introvert and video game addict. Secretly gay, Andrew is viciously bullied by classmates and only finds comfort and courage at Ernie’s Arcade where he discovers a mysterious, never-played arcade game called Polybius, and investigates its dark and bloody provenance.

Hailing from RocketJump and distributed by Lionsgate, “Dimension 404” aims to evoke that 3 a.m. feeling of wandering onto the weird side of the web, stumbling upon stories that cannot be explained in the world that we know.

“Dimension 404” is created by Dez Dolly and Will Campos. Co-Creators are Dan Johnson and David Welch. The series is executive produced and directed by Freddie Wong, Matthew Arnold and Dolly, who will also serve as showrunner.
