Now that “Furious 7” was a colossal hit both in the box office and fans, an eighth installment in the popular action/racing franchise is rapidly making its way into theaters. With a director, most of the principal cast and fans already in place, the only thing missing seems to be the title -- which series helmer Vin Diesel says even he doesn’t know. 

For those that have been paying attention, the “Fast and Furious” franchise doesn’t often cycle the same movie title twice. The series started as “The Fast and the Furious,” then quickly became “2 Fast 2 Furious,” followed by “Fast and the Furious: Tokyo Drift,” which proceeded a slew of other title changes that led to 2015’s “Furious 7.” Now, with the eighth installment on the tip of every action junkie’s tongue, fans are eagerly waiting for Diesel and the producers to give the official word on what to call the 2017 film. Unfortunately, that wait might be longer than many think.

Speaking to MTV News, Diesel revealed that, although he’s been calling it “Fast 8” in the press and on social media, he has no clue what the next installment will be titled. 

“A lot of people are thinking ’F8,’ I just get lazy and say ’Fast 8′,” Diesel said. “I don’t know if the official title’s come out yet. It’s never the official title. You have to understand. When you talk about titles and you talk about ’The Fast and the Furious’ the first movie all through production the back of my chair said 'Red Line.’ This is like, this is par for the course for the ’Fast’ franchise. We never know what the title is officially. Guys like me, they can get a little lazy with titles. I say ’Fast 8.'”

According to Variety, Diesel previously revealed on his Facebook page that “Furious 8” (or “Fast 8” or “Fast and Furious 8” or “F8” or “Furious 8: The Goblet Of Mockinjay’s Two Towers, Part 1”) will kick off a final trilogy of movies, presumably culminating in a tenth installment to finish out the unprecedentedly successful franchise. As a result, when asked by MTV, in the video below, if he already knows how the story of Dominic Toretto will end, the actor was able to issue an emphatic “yes” in response. 

Unfortunately, Diesel is playing all of these plot cards very close to the vest. So far all that’s known about “Furious 8” is that it will take place in New York City. Fans will just have to wait until the movie hits theaters on April 14, 2017 to find out what’s next.
