Director David Twohy on how he Crafted the Riddick Trilogy’s Exoplanets

The basic premise behind each installment of writer and director David Twohy’s sci-fi film trilogy—Pitch Black, The Chronicles of Riddick and Riddick—is pretty straightforward. Riddick, played by Vin Diesel, finds himself on a hostile alien planet inhabited by creatures that want to kill him. To add flare to what otherwise could become a tired storyline, Twohy constructs his films around dramatic human storylines and builds them up from a foundation of real-world science.
