The much-awaited Arrow and The Flash spinoff series Legends of Tomorrow finally premieres this week and fans could not be more excited. Legends is set to further expand the DC's TV Universe – and viewers who don't necessarily follow Arrow or The Flash, need not worry about losing the plot as there will be enough time spent on the backstory of characters.

"I don't think you need to watch Arrow and Flash to appreciate what it is Legends has to offer," actor Wentworth Miller (who plays the supervillain/anithero Captain Cold) told IGN. "The beauty of this show – and they do this on Flash, and they did this on Arrow – is that we do spend time on character. We do spend time on backstory. We do take a moment in between the sci-fi special effects to tell you who these people are, so that when something happens to them, you actually care."

That being said, you can expect lots of crossovers, with Arrow and The Flash set to appear on the show. Executive producer Phil Klemmer recently confirmed that older as well as younger versions of Arrow and Flash will feature in Legends of Tomorrow.

DC's Legends of Tomorrow premieres on Thursday, 21 January on The CW. Check out the premiere episode synopsis below:

In the year 2166, the immortal villain Vandal Savage (Casper Crump) is on the verge of his final victory – total chaos and the utter destruction of humanity. As the world crumbles, the Time Master Rip Hunter (Arthur Darvill) takes matters into his own hands; he travels 150 years into the past to assemble a carefully selected team of heroes and rogues to stop him.

Hunter has chosen what seems like an ill-matched group: billionaire inventor Ray Palmer (Brandon Routh), who has created an exo-suit with the power to shrink him to miniscule size, as the Atom; Sara Lance (Caity Lotz), the White Canary, a trained assassin; Professor Martin Stein (Victor Garber) and Jefferson "Jax" Jackson (Franz Drameh), who together form the meta-human Firestorm; Leonard Snart (Wentworth Miller), known as Captain Cold, and his partner Mick Rory (Dominic Purcell), aka Heat Wave, a pair of career criminals; and Kendra Saunders (Ciara Renée) and Carter Hall (Falk Hentschel) aka Hawkgirl and Hawkman.
