Plot details are being kept under wraps, however, Chris Pine, Zachary Quinto, Karl Urban and Zoe Saldana are expected to return to the franchise, per Deadline.
The Abrams-directed Star Trek, starring Pine and Quinto, was released in 2009, with its sequel, Star Trek Into Darkness, coming out in 2013. The third film, Star Trek Beyond, was released in 2016 and was directed by Justin Lin. It was also Anton Yelchin's final Star Trek film, before his traffic death that year.
Earlier this year, John Cho, who portrays Sulu in the films, told ET that he was "optimistic" that a fourth film would still happen.
"I certainly am down, and to be honest," Cho expressed. "Somebody at some point will all get on the same page and just do it. That's my belief, maybe I'm being optimistic."
