DC’s Legends Crossover & Time Travel Talk

“DC’s Legends of Tomorrow” executive producer Phil Klemmer has confirmed that alternate versions of Barry Allen and Oliver Queen are locked to appear on the time-traveling anthology series.

Speaking with EW at the Television Critics Association’s press tour on Sunday, executive producer Greg Berlanti was asked about the show potentially sporting crossover with its predecessors “Arrow” and “The Flash”. He says:

“It’s intermittent throughout. Because they’re a band of time traveling rogues, it’s harder for Arrow and Flash to be connected story wise to it throughout the season. That being said, if you know the histories of Arrow and Flash, it should be extra fun in its own way as we delve deeper and deeper into the characters lives.”

Klemmer then said that there is a “100 percent chance that older and/or younger versions of Oliver Queen (Stephen Amell) and Barry Allen (Grant Gustin) will appear.” They would join the already confirmed Cisco Ramon (Carlos Valdes), Damien Darhk (Neal McDonough), and Ra’s al Ghul (Matt Nable) who will cameo on the show. Klemmer adds: “We will have a couple marked crossover moments that hopefully will keep people satisfied.”

Talking about the rules of time travel on the show, Berlanti says:

“We try to exist by the rules we establish for ourselves. Our real goal is to make something emotionally true and truthful. Whenever we can have conversations about time travel, I always ask my questions in terms of Back to the Future or 12 Monkeys and use other examples that have preexisted. As Andrew [Kreisberg] says, as far as we know, time travel is not real. If there were an actual rulebook we could read and learn, we would follow that. We try and follow whatever rules we establish for ourselves. All the characters are learning as they go along. As we go along and establish rules, some of which we’ve established on Flash, the audience is learning it too.”

One such rule is that characters cannot visit an event in which they participated. Klemmer says that was done for a specific reason:

“We make rules that make good drama. We gave up our Get Out of Jail Free card so it wouldn’t become Groundhog Day where if someone died we’d just keep going back again and again. It’s important to have consequences and real deaths on the show.”

“DC’s Legends of Tomorrow” premieres Thursday, January 21st.
