If Jim Carrey is the kind of actor who can change his facial expressions at will, then Kevin Spacey is the kind who can change his character at will. If you watch his work consecutively, you'll find that one moment he's a rude guy swearing his head off, and the next he's turned into a cold-blooded killer devoid of humanity, and then a cowardly man fearful of everything. From an actor's standpoint, he is undoubtedly outstanding.
David Fincher, on the other hand, is one of the directors Adrian greatly admires. First, he knows how to tell a story; second, while telling stories, he retains a sharpness that's his own. Spielberg is perhaps the best at storytelling among directors, yet often he inevitably bows to commercial and entertainment demands. Fincher seldom does this, and yet he doesn't fall into the trap, like some auteur filmmakers, of only expressing personal views without considering the audience. He combines appeal with unique thoughtfulness—a rare kind of director.
