Disney, HBOTo get into his villainous character Kylo Ren in “Star Wars: The Force Awakens,” Adam Driver would yell before shooting, sometimes resulting in sound guys turning their microphones down.

This “Wonderful ferocity” made him “Perfect” for the role, director J.J. Abrams revealed during a Sirius XM Town Hall recording with People and Entertainment Weekly editorial director Jess Cagle after being asked which actor was more like their character.

“Adam Driver, t are times when he’s so hard on himself as an actor,” Abrams said.

Driver would have to rile himself up as mental preparation.

In a 2014 cover story for GQ, Driver is described as having “Equal amounts of twitchy intensity and feral grace,” applying both his military background and Julliard training to the roles he takes on.

Abrams added that all of the actors, both old and new, “All brought themselves in an incredible way to each of the characters.”
