February marks a decade since it was first reported by Variety that Adam Driver would join the cast of the highly-anticipated Star Wars: Episode VII as a character "in the vein of iconic villain Darth Vader.” That character turned out to be Kylo Ren, a powerful dark side user with a moral complexity and ties to the past. Kylo Ren ultimately follows a similar path to Darth Vader by turning on the light before meeting his demise, but Driver recently shared that wasn't always the plan.
