And it's... alright. From the About section:
The Multiverse is the Home Planet of Scripted Geek Entertainment.
For fans of Sci-Fi, Superheroes, Paranormal and Fantasy, The Multiverse is home to a sorting hat-full of original series and short films, from spoof comedies to cutting edge science fiction and fantasy adventures.
Captained by Fleet Commander Warwick Davis - legendary star of Harry Potter, Star Wars, Hitchhiker's Guide, Willow, Jack the Giant Slayer... who's looking to bullseye more than a few womprats.
The Sci-Fi shorts and the videos with Warwick in them are pretty good. The rest are generally forgettable low budget videos. I haven't come close to watching them all, but the ones I randomly picked were pretty bad.
I am looking forward to Dwarves Assemble though. The trailer for it is the video up top. The video below is Warwick visiting the Yogscast office to pitch the Dwarves Assemble idea to Simon from the Yogscast. It's pretty funny.
Oh, and there's a second Multiverse channel called Multiverse2 with behind-the-scenes stuff, interviews, how-tos, and more.
