While "Star Trek Beyond" doesn't hit U.S. theaters until this summer, Paramount Pictures is already gearing up for "Star Trek 4". However, with Justin Lin rumored to be circling "Space Jam 2" movie, Paramount may need another director to take on the next installment of "Star Trek", AceShowbiz said.

As AceShowbiz reports citing TrekMovie.com, Paramount officially registered the title "Star Trek 4" with the Motion Picture Association of America on Saturday, April 30. It's highly doubtful that the studio is re-registering the 1986 "Star Trek IV: The Voyage Home" instead of a new sequel.

While registering with the MPAA isn't a guarantee that the sequel to "Star Trek Beyond" will actually happen, keep in mind that Chris Pine (Captain Kirk) and Zachary Quinto (Spock) have already signed on for a fourth film.

"Star Trek 4" is simply a placeholder until production is underway and an official title can be chosen.

Directed by Justin from Simon Pegg and Doug Jung's screenplay, "Star Trek Beyond", starring Chris, Zachary, Zoe Saldana, John Cho, Anton Yelchin and Idris Elba, is set to be released in the U.S. on July 22.
