This year marks the 50th Anniversary of the iconic Star Trek franchise, with Paramount helping to celebrate by releasing the highly-anticipated sequel Star Trek Beyond, in theaters July 22. While we don't know if any more footage will be released between now and then, stars Zoe Saldana (Uhura) and Zachary Quinto (Spock) recently shed new light on this latest adventure. We know this follow-up is set in the midst of the U.S.S. Enterprise's five-year mission, and it seems their work has taken quite the toll on these crew members.

Entertainment Weekly caught up with both Zoe Saldana and Zachary Quinto after their taping of last week's episode of Lip Sync Battle, where they shared new insight into the story. Zoe Saldana reveals that, when the plot picks up, the entire crew is just exhausted. Here's what she had to say about the crew needing a break.

"We're tired, we need time off, we've been working non-stop, and it's become like a machine where you kind of forget about yourself, but you need to go back home and nurture yourself and rest," she explains. "Life has a different journey for us, and instead of us having to go out and aid another population, another planet that has been the target of violence, we are the target, so this is very different. We are tested at the craziest level and not just our lives are tested, but our characters and our relationships are tested."

Zachary Quinto also teased that Spock will be facing some existential challenges in Star Trek Beyond. This iconic character will continue to grapple with his Vulcan roots, and he will finally realize the best path for him in this movie. Here's what the actor had to say below.

"(He) is in this existential moment in his life and at a crossroads between his obligation to his Starfleet and his Vulcan roots. His planet was destroyed and they're rebuilding, and he's trying to figure out where his energy is best directed to help other people. He comes into a new awareness of his own mortality for a number of reasons, and there's a lot of stuff that he's trying to figure out in this film. By the end, I think he realizes the best path for himself moving forward. We spend a lot of time with unusual compatriots, like Kirk [Chris Pine] and Chekov [Anton Yelchin], Sulu [John Cho] and Uhura, and Spock and Bones [Karl Urban]. All of us are working to find our way back to one another and to join forces in order to defeat our common adversary."

Star Trek Beyond is the highly anticipated next installment in the globally popular Star Trek franchise, created by Gene Roddenberry and reintroduced by J.J. Abrams in 2009, returns with director Justin Lin ("The Fast and the Furious" franchise) at the helm of this epic voyage of the U.S.S. Enterprise and her intrepid crew. In "Beyond," the Enterprise crew explores the furthest reaches of uncharted space, where they encounter a mysterious new enemy who puts them and everything the Federation stands for to the test. Zachary Quinto also reveals that Spock is trying to figure out his relationship with Uhura.

"Part of Spock's existential crisis is, does he need to be with a Vulcan? Uhura recognizes this, so they're not necessarily at the height of relationship bliss in this film, but they love each other deeply and they want each other to be happy, to be fulfilled, to serve their purpose, and to realize their potential. It's an ongoing relationship; I don't think that it's resolved necessarily in Star Trek Beyond. They're learning about each other as well and figuring out the best way for each of them to move forward. You'll have to see where it goes."

The film stars Chris Pine as Captain Kirk, Zachary Quinto as Spock, Zoë Saldana as Uhura, Karl Urban as Bones, John Cho as Sulu, Simon Pegg as Scotty, Anton Yelchin as Chekov and Idris Elba as the new villain Krall. Directed by Justin Lin, the third film in the franchise series is produced by J.J. Abrams, Roberto Orci, Lindsey Weber and Lin; and executive produced by Jeffrey Chernov, David Ellison, Dana Goldberg, and Tommy Harper. Based upon the Star Trek TV series created by Gene Roddenberry, the screenplay is written by Pegg & Doug Jung. Stay tuned for more on Star Trek Beyond as we get closer to the July 22 release date.
