The visual effects company MPC also spent a specific amount of time then reworking the hair shots to make sure hair was colliding and movie in slow motion.
In other words, the process was complex, similar to how Merida’s animated hair in Brave was complex.
It took a lot of special effects to get Javier Bardem’s Salazar and his crew looking like they came from under the water.
That underwater-like atmosphere translated the most into Bardem’s hair for the movie, and Pirates of the Caribbean 5 ended up getting proprietary software called Furtility that helped create millions of hair strands that were able to move in very specific ways.
