Hollywood is an important part of popular culture, to the point where many of us idolize the writers, directors, and actors who make our favorite films a reality. We see the creative output of their endeavors and dream of being able to do work like that. But at the end of the day, acting (and writing, and directing), as glamorous as it can seem, is still just a job. Actors are people like you and me, and they’ve got to pay their mortgage and feed their families. Sure, sometimes actors are lucky enough to pick and choose the projects they do, but most have to take what they can get because they’ve got bills to pay.
Also: the actor who plays Stewart may be an alcoholic.
