Vin Diesel says that a potential fourth film in the "Riddick" franchise, should it go ahead, is some time off. He tells Maria Menounos:
"It's a miracle that Riddick exists, it's a miracle that we're back on the boards, it's a miracle that we just unlocked the key to the continuation of this franchise.
I don't want to mislead anybody with the recent success of Fast & Furious. I'm not going to be able to do Riddick at the same pace as Fast & Furious. It's just… It's just too dark."
"Riddick" director David Twohy says he and Diesel believe there are "two more movies" left in the franchise. He tells Screenrant:
"I think it's good that we are looking at ending the series so it doesn't feel like an open-ended thing, like we're doing it just for monetary reasons… I think there's a real end to this and I know what that last movie looks like. The real question is: is it like a two-parter rather than a one-parter? So I think we're both thinking the same thing, that there's two more movies in the series."
That last one will be set on Riddick's home planet of Furya:
"That's where we end up. I know what that movie looks like, I've talked it out. It has all the right notes, it's a great movie. The real question is: what do you do before you get there? Is it a voyage through the Necromonger universe? Do you have to earn the right to return home by some trial of fire? That's what we're talking about doing. Perhaps"
