Television's superhero invasion continues over the next couple of weeks with the seasonal returns of The Flash (year three), Arrow (year five), Supergirl (year two) and DC's Legends Of Tomorrow (year two).
To celebrate, in America the CW network (the shows will be airing on Sky1 in the UK) has released a new promotional trailer — a portion of which is above — that brings together characters from all four series, including Grant Gustin as Barry Allen/The Flash, Melissa Benoist as Kara Danvers/Supergirl, Stephen Amell as Oliver Queen/Green Arrow and Brandon Routh as Ray Palmer/The Atom. All of those characters are participating in their own take on Fight Club.
