"[M]y partner on [The Chronicles of Riddick] since the beginning, [David Twohy]... has a new challenge in store....He wants me to have 3 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."
