In case you're wondering how different Legends of Tomorrow from its origins, The Flash and Arrow, we have the answers.
Here's how showrunner Phil Klemmer explains the vibe of the spinoff:
This is real different. It takes place on a spaceship that travels through time, and arrives in different eras and locations. It is sort of divided into chapters that are serialized. It's not episodic, bad guy of the week, it is two or three or four episodes in a time period.
We want to do the greatest hits of the 20th century. Without giving away spoilers, it's like, if you had a time machine, where would you go? Where would you intervene? Trying to imagine Vandal Savage as the devil in "Sympathy for the Devil" -- imagining that this guy's been going through history, dipping his fingers in human events, and steering the course of history for his own evil purposes.
That's the fun of our show; trying to find him and intercept him at these points in history where the balance seemed tipped, whether that's Cold War, nuclear annihilation or World War II fascism, you name it. If bad s-h-star-star was happening, Vandal was there. The fun of our show is encountering him in these iconic, 20th century crucible moments.
