CW's doing an 'Arrow'-'Flash' spinoff called 'DC's Legends of Tomorrow' - Watch the first trailer

Heroes, villains, epic battles and time travel - That's what fans can expect from The CW's "Arrow"-"Flash" spinoff "DC's Legends of Tomorrow."

The network released the first trailer from the spinoff on Thursday and it does a pretty thorough job of explaining the show's premise - even if you're not caught up on the happenings of "Arrow" and "Flash."

A motley crew of super heroes are brought together by Arrow (Stephen Amell) and Flash (Grant Gustin) to face the greatest threat the world has ever experienced. They'll be led by a man from the future, Rip Hunter ("Doctor Who's" Arthur Darvill). Although it doesn't look like it at first, the crew will actually become a team and as the show's title suggests "legends."

It also stars Victor Garber ("Alias"); Brandon Routh ("Superman Returns"); Caity Lotz ("Arrow"); Ciarra Renee ("Pippin"); Franz Drameh ("Edge of Tomorrow"), and "Prison Break" alums Dominic Purcell and Wentworth Miller.

"DC's Legends of Tomorrow" will premiere in the midseason on The CW.
