The Avengers
When Mark Ruffalo was first approached about playing the Hulk in The Avengers, he was hesitant to accept the role, believing he was the wrong fit. However, Ruffalo caved, and soon became the man in the motion-capture suit seen above. Ruffalo has called the process of evolving into his character "humiliating" due to his "man-cancelling suit," saying that the tight leotard "makes you look big where you want to look small and small where you want to look big."
Sin City
The Sin City franchise is famous for its use of CGI, which brought the comic book movie to life like none other.
"People have accused me of realism in the past. Not guilty as charged. My stuff is very stylized," said Frank Miller, author of the Sin City comics. "Robert [Rodriguez] was able to show me how real actors could perform within the universe that I drew and then to amplify that further. Technology has improved [that] dramatically over the last 10 years."
