Samuel L. Jackson's most badass movie moments

"187" (1997)

Jackson carries this action-driven inner-city-teacher flick that starts off as a thoughtful character study and transforms into an intense showdown between the teacher and gangbanger students in Los Angeles.

Badass moment: The teacher, emotionally raw after having been brutally stabbed by a student in New York, demands a game of Russian roulette with young thug Cesar, repeatedly pulling the trigger of the gun to his own head.
