After spending time in the '70s and '80s, "Legends of Tomorrow's" ragtag Waverider crew will journey into the future to the year 2046 -- and they're going to learn that the future isn't so welcoming. TV Line caught up with the "Legends" cast to learn more about the team's trip to the futuristic (and a bit dystopian) Star City.

"It's not a very happy place," said Caity Lotz, whose Sara Lance debuted on "Arrow" and now stars on "Legends." "It's a Disneyland for criminals, so I don't think Rory [Heat Wave] and Snart [Captain Cold] mind it too much." But the show's two ex-Star City residents, Lotz's Lance and Brandon Routh's Ray Palmer, will not react well to seeing their city in such a state. "One of the reasons this happened is because I wasn't there to help," Lotz told TV Line, referring to herself in character. Routh added that Star City will have changed in a personal way for Ray Palmer as well, and the Palmer Tech building will sport a different logo.

The team will also run into a few archers: Connor Hawke, played by Joseph David-Jones, and an even more grizzled and older Oliver Queen ("Arrow" lead Stephen Amell). To show how rough the past 30 years have been, Amell's character will have a beard and a prosthetic arm.

"Oliver is jaded, hard, and a little bitter," Lotz said. "He failed the city. Everyone failed the city... I think we work really well off of each other. [Sara and Oliver] always have such good chemistry."

Overall, Arthur Darvill (who plays Rip Hunter) said to TV Line the episode is "one of the first episodes that felt like we were shooting a big movie. There are a couple of really good fights in it, and there are some big, big set pieces that up the scale of the show. It has a very different feel than the rest of the season."

The "Star City 2046" episode of "Legends of Tomorrow" airs this Thursday on the CW.
