After the blockbuster reception for Furious 7, Vin Diesel has revealed a clue about the possibility of an eighth instalment of the American action movie.

Walker's co-star and friend Vin Diesel, has said that the next instalment in the action thriller movie franchise is guaranteed and also hinted that Furious 7 was a tribute to his late brother, while F8 will start from Walker.

"Well, I was trying to keep it close to the vest throughout the release. Paul [Walker] used to say that eight was guaranteed. And in some ways, when your brother guarantees something, you sometimes feel like you have to make sure it comes to pass," Diesel said during the MTV Movie Awards 2015.

"So if fate has it, fate..F8...if fate has it, then you'll get this when you hear about it. Seven was for Paul, eight is from Paul," he added.

Meanwhile, the producers of the blockbuster franchise are looking for the perfect replacement for Walker and are exploring other characters in the popular franchise. He also hinted that three more movies will be produced from the Fast and Furious franchise.

"We think there's at least three more. Paul is, and always will be, an integral part of the story. But there are many other great characters, and it's also an opportunity to introduce new characters," Universal's chairman Donna Langley told Hollywood Reporter.

"I think it's still a growing franchise. We'll see what happens with Furious 7, obviously, but our box office has grown over the past three or four films and internationally, in particular. So we think that there's more to mine there. But we're of course very mindful about fatigue," she added.
