Vin Diesel has hinted at some of the idea behind the next instalment in the Riddick series.
We last saw Diesel take on the role of Riddick back in 2004 with The Chronicles of Riddick but he and series director David Twohy are set to return.
Writing on Facebook the actor said: "[M]y partner on [The Chronicles Of Riddick] since the beginning, [David Twohy]... has a new challenge in store.
"He wants me to have three different body looks for this next chapter.
"There is the DiNorscio type, the Dom type, and the lean Furyan type... but all in the same movie, haha... When it comes to art, we all like a challenge."
We haven't seen Diesel on the big screen since Fast & Furious last year and it's with this franchise that he will return as Fast Five is set to hit cinemas in the summer of 2011.
He is also due to reprise the role of Xander Cage as xXx: The Return of Xander Cage is in the pipeline.
