After the recent box office success of “Furious 7,” an eighth installment to the franchise is inevitable. However, there are quite a few speed bumps in the way of Fast 8’s production.

“Furious 7” has made $392.3 million and has quickly become the franchise’s most lucrative sequel, which has many speculating about the follow-up film. “Honestly, we’re just bathing in the success of this,” producer Neal Moritz tells The Hollywood Reporter. “We’ll probably get together in a week or so to talk.”

The plan of Universal Studios is to make 10 Fast and Furious films according to a statement made in 2014 by chairman Donna Langley. Multiple sources have confirmed that this is still the plan. However, several significant setbacks must be overcome before production begins on the next movie.

One of the biggest issues is that a writer has yet to be hired for the next go-around. However, lack of script has never stopped the franchise in the past. Fast and Furious films tend to be planned unlike any other movies: first a release date is scheduled, then star/producer Vin Diesel meets with Moritz, copyist Chris Morgan and a director to create the story.  They come up with the complicated stunts and sets and then add a story in order to pull everything together.

As of now, however, there still is nobody in the director’s chair. James Wan was the original director for “Furious 7” and had signed a two-picture option when he joined the team. Yet after the difficult filming process that was necessary following the death of Paul Walker halfway into production in 2013, he departed to work on “The Conjuring 2.” Sources have said that he’s going to be filming the follow-up to the horror film this October. Universal might wait until he is done working on that film to begin work on “Fast 8” or they may opt for another director. The studio is currently receiving calls from various agents but have not released a list of possible directors as of yet.

This hasn’t stopped the franchise’s star from developing ideas. Diesel recently mentioned he wants the newest project to be set in New York.

“[The story] is going to have to be something enticing for all of us,” Moritz said. “It has to be as good as or better [than ‘Furious 7’].”  According to inside sources, many of the casts’ options have expired, so the newest movie would require significant negotiations. This includes Dwayne Johnson, who came on during “Fast Five” and negotiates deals on a film-by-film basis.

The first step in making the movie will be for Universal to establish a release date, which could come later this April during the CinemaCon convention.
