Hulu’s upcoming anthology series Dimension 404 sounds interesting, if nothing else — the “404” of the title is the all-too-familiar error code you get when you try to visit a web page your browser can’t find, and according to Deadline Hollywood, the show “aims to evoke that 3 AM feeling of wandering onto the weird side of the web and stumbling upon stories that cannot be explained in the world that we know.” If internet paranoia/paranormal sounds like your cup of tea, then you may well also appreciate the news that both Megan Mullally (Will & Grace/Childrens Hospital) and Constance Wu (Fresh Off the Boat) have joined the show’s cast — they’re both guest stars in one of the show’s six episodes. Hurrah.
