Star Trekis in a bit of an interesting place right now. Fans are very excited aboutStar Trek: Discovery, the new show that CBS is developing, despite several delays in the process. There is also the prospect ofStar Trek 4, which was in the works beforeStar Trek Beyondeven hit theaters last summer. But fans of the currentStar Trekmovie franchise may not want to get too excited yet, because the movie is not a guarantee, according to Zachary Quinto.

The actor recently appeared onThe Today Showto talk about his new indie movieAardvark, but he could avoid talking aboutStar Treka little bit. When asked if he could provide any insight about the in developmentStar Trek 4, Zachary Quinto, who plays youngSpockrevealed that the script is being worked on, but that the movie is not a sure thing in terms of actually getting made at this point. Here is what he had to say about it.

“I know that they are working on a script for another one and we’ll see how that all plays out, but the nice thing about that experience is that the time in between those big tentpole films allows us to go off and cultivate a lot of different creative experiences for ourselves…I’m hopeful that we’ll do another one, but there’s no guarantee.”

Star Trek Beyondwas a bit of a strange occurrence. The movie was wholly embraced by fans and critics, with the movie currently holding a very positive 84 percent approval rating on Rotten Tomatoes. Unfortunately, the acclaim didn’t really translate to box office success. The movie grossed a total of $343.4 million at the worldwide box office. That number may seem fine on the surface, but when the massive $185 million production budget is factored in, which doesn’t account for marketing, the movie didn’t do very well at all. If Paramount turned a profit, it was likely minimal. So that is probably whyStar Trek 4is not a sure thing.

IfStar Trek 4does wind up happening, we already know a good bit about what we can expect from it. It has already been revealed thatChris Hemsworthwill be returning asGeorge Kirk. In case you forgot, Hemsworth appeared briefly, but memorably, in 2009’sStar Trekas James Kirk’s father, who bravely sacrificed himself at the hands of the Romulans in order to save thousands of lives, including his newborn son. That meansStar Trek 4would unite James Kirk, played by Chris Pine, with his father on screen, which is something that could really appeal to both new and old fans ofStar Trek. Especially considering that Chris Hemsworth has become a much bigger star in the years since appearing as George Kirk initially.

Simon Pegg, who co-wrote the script forStar Trek Beyond, teased on Twitter late last year that he was already working on the script forStar Trek 4with Doug Jung. It is also expected that Justin Lin will return to direct, with J.J. Abrams producing, assuming the movie does wind up getting the green light.
