ROGER GUENVEUR SMITH AS SMILEY IN DO THE RIGHT THING (1989)
M-M-M-Malcolm X and M-M-M-Martin Luther King, Jr. are the obsession of this mentally handicapped stutterer who finally gets a picture of a black man on the Wall of Fame in Sal's Pizzeria by setting fire to the joint in a race riot and putting one up on his own. You might think "slow" folks who stutter are harmless but you'd be wr-wr-wr—incorrect.
