Robin Williams in "Homicide: Life on the Street" : Robin Williams booked a co-starring role on the critically-hailed, broadcast network precursor to "The Wire" as a distressed father in 1994. In the clip below, you'll see a young Jake Gyllenhaal as his son. Williams was best known for his theater-esque pipes, boasting a tremendous voice often accompanied by some silly antics, but he was also an actor with immense restraint. Here, he conveys loss, concern, and fear in such a way as not to take away anything from the drama unfolding in the scene. He's supporting the script rather than overpowering it, noting a critical self-awareness he brought to each of his many roles.
