Hulu’s upcoming sci-fi anthology series Dimension 404 is filling out its cast.

Joel McHale and Sarah Hyland have joined the six-episode drama from RocketJump's Freddie Wong, Matthew Arnold and Dez Dolly. They join a cast that already includes Lea Michele — who will play Amanda, a witty, ambitious, type-A girl with a warm heart who turns to matchmaker services to suit her rebound dating needs after a bad breakup — and Robert Buckley, who will star as Adam, a guy who falls hard for Amanda after an online date and whose breakup forces him to confront a series of truths about his life.

McHale (Community) has been cast in Michele and Buckley's episode of Dimension 404 as Mr. Maker, a charismatic, eccentric and slightly patronizing founder of a matchmaking company that offers single adults a seemingly perfect solution to finding love. The actor can next be seen CBS' The Great Indoors, and also has an upcoming book, Thanks for the Money, due out in October.

Modern Family vet Hyland will play Chloe, the female lead in another stand-alone episode of the hourlong drama. Chloe is an unassumingly cute, 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 and best pal, Dusty, to take her to a screening of a new sci-fi/action film in a fresh, never-before-seen cinematic format called "Cinethrax," which gives the audience a strange, perilous moviegoing experience. Hyland can next be seen in ABC's remake of Dirty Dancing.

Distributed by Lionsgate, the anthology series draws inspiration from the internet’s notorious "404" error code and aims to evoke the feeling of wandering onto the weird side of the web at 3 a.m., stumbling upon stories that cannot be explained in the world as we know it. Among the sorts of questions explored in the series: What if an obscure cartoon held the secret to time travel? What if energy drinks caused the apocalypse? What if the NSA’s top analyst was a gigantic, all-knowing cube of sentient meat named Bob?

Dimension 404 is created by Dolly and Will Campos, with co-creators Dan Johnson and David Welch. Executive producers include Arnold, Dolly, who also will serve as showrunner, and Wong, who will direct.
