Tonight's episode of DC's Legends of Tomorrow will wrap up the four-night "Invasion!" crossover event, and to get your prepared for what's to come, The CW has put out a new featurette in which Executive Producer Marc Guggenheim previews the episode.
"Episode seven is the climactic episode of our epic annual crossover between Supergirl, Flash, Arrow, and now the Legends of Tomorrow," Guggenheim says in the featurette. "It was written by myself, Phil Klemmer, and Greg Berlanti, directed by Gregory Smith. It is a beyond epic conflagration, featuring all the superheroes we've established, across all four shows, fighting alien invaders. It's quite simply the biggest hour of television we've ever produced."
ALL FOR ONE AND ONE FOR ALL IN THIS CROSSOVER OF SUPERHEROS -- After learning the Dominators' plan for the world, the Legends must work together with The Flash (guest star Grant Gustin), Supergirl (guest star Melissa Benoist) and Green Arrow (guest star Stephen Amell) to kill them once and for all. Meanwhile, Stein (Victor Garber) figures out, with the help of others, how the team can terminate the Dominators, but is distracted by the aberration he realizes he created in 1987. Brandon Routh, Franz Drameh, Dominic Purcell, Maisie Richardson-Sellers, Nick Zano and Caity Lotz also star.
Gregory Smith directed the episode written by Phil Klemmer & Marc Guggenheim.
