About this series

Stuart Fails to Save the Universe is a spin-off of beloved US sitcom The Big Bang Theory and the newest instalment in the hit franchise. Stuart Bloom, eccentric comic book store owner and friend of the quirky gang of physicists from the original series, may or may not have ripped a hole in reality. Oops.

After breaking a device built by genius besties (and frequent patrons of The Comic Center of Pasadena) Sheldon Cooper and Leonard Hofstadter, Stuart Bloom incites an all-out multiverse war. And it's up to him, his friends, and his girlfriend to find a way to fix it. No pressure, then.

Unlike other stories within The Big Bang Theory world, Stuart Fails the Save the Universe is a wild ride of sci-fi adventure, action, and exploration, meeting alternate versions of some of our favourite characters from the wider Big Bang Theory television universe.

Can Stuart keep his livelihood and relationship afloat while he tries to save the world as we know it? Tune into this The Big Bang Theory spin-off to find out.
