Gary Oldman In True Romance (1993)

As he personifies the type of human garbage that engages in the flesh-peddling business, Oldman's portrayal of Spivey as a deranged and demented pimp is compelling. Oldman surely made the most of his one scene in the movie with his hazy eye, scarred visage, and scarcely understandable language.
That whole scene with the girl in #29 made me wince. It was hard to watch, but then so was the whole movie.
This.
