DC’s TV universe is about to expand with Legends of Tomorrow, a time-traveling superhero series, that is a spin-off to The flash and Arrow. 

The show revolves around the adventures of the supporting characters from the Flash and Arrow. 

The series debuts in the US on January 21st, no UK broadcaster has been announced yet. But I would be very surprised if Sky One didn’t pick this up. 

Here’s the synopsis:
When heroes alone are not enough… the world needs legends. Having seen the future, one he will desperately try to prevent from happening, time-traveling rogue Rip Hunter is tasked with assembling a disparate group of both heroes and villains to confront an unstoppable threat — one in which not only is the planet at stake, but all of time itself. Can this ragtag team defeat an immortal threat unlike anything they have ever known?
