The Flash Team Talk Time Travel Episode

All things considered, it seems to be an appropriately timed story. It was Groundhog Day yesterday, and suddenly we're talking time travel. “The Flash” star Grant Gustin says their upcoming time travel episode of the series will take some of its ideas from the movie Groundhog Day. 

It’s a complete accident the first time [he time travels]. It’s really confusing because now we’re playing with timelines and we’re having to shoot things a couple different ways. It’s like a Groundhog’s Day-type element. It’s really funny and really exciting.

He’s not handling it incredibly well. It’s freaking him out a little bit. He realizes, ‘Holy s**t, this an opportunity to change things with my family’s past,’ He doesn’t know yet to maybe not do that, but that’s where Barry’s at when he realizes what he’s just learned that he can do, that he can maybe save his mom.

Many have theorized that Barry himself was present the night of his mother’s murder and perhaps the reason he appeared miles away as a child that night was his older self saving him. When asked about this, Gustin replied: “That’s a good theory.”

There’s an episode coming up where there is inadvertent connection to the Speed Force that results in probably our funniest hour as well as our darkest hour as the dangers of time travel come to light. It’s a mashup between Back to the Future and Terminator—the good version of time travel and the bad version of time travel.
— Andrew Kreisberg, Executive Producer

Kreisberg offered one more tease, saying, “After that episode, things are never going to be the same on The Flash.”

“The Flash” airs Tuesdays at 8 P.M. EST on The CW.
