Even though Vin Diesel was one of the founding stars of the Fast and Furious Franchise, the franchise is starting to experiment with what it can do without the star. There is a spin-off in the works with Dwayne Johnson and Jason Statham. There have been many reasons that are given for this spin-off. One reason that has been given is that they are waiting for the right director to come back so that he can be the one to film the last two. They are talking about Justin Lin of course. However, there is another director who has expressed interest in coming back to the Fast and Furious franchise. He is the director of the first ever Fast and Furious movie back in 2001, Rob Cohen. Both Justin Lin and Rob Cohen have one thing in common. They have both launched the franchise at different phases.
There is a new sub-franchise that is getting ready to be launched, and this is the team up of Hobbs and Shaw. While it is good for them to branch out, it could fail. After all, even the star power of Dwayne Johnson is not going to save the film if the story turns out to be lacking.
If it does turn out to be a success, then the Fast and Furious franchise has found a way to continue on even after the 10th movie where all of the principle characters retire. They may make appearances in the background depending on how the last film goes. After all, they will raise the stakes in the final film so it is likely some key characters are going to die.
