10 Supporting Film Characters That Completely Stole The Spotlight

6. Aaron Stampler (Edward Norton) - Primal Fear

This sweeping, twisting courtroom drama was devilishly surprising and tense throughout: it was a totally engaging and thought-provoking experience that played with the audience nicely, but the suspense and entertainment were provided almost entirely by Norton's character, Stampler.

The Oscar nom for Norton really kickstarted his career, and justifiably so, for his performance was absolutely and totally convincing opposite lead Richard Gere. Stampler is at times disturbing and unsettling to watch, with manifestations of schizophrenia as a would-be murderer. He's utterly chilling, with a problematic and well-worked back story providing the real meat in the story. You simply cannot take your eyes off Norton, who you can tell has researched and practiced his character thoroughly in preparation.

His stuttering delivery, intense stare and obvious psychological torment make him the obvious talking point of the film, and it's hard to see it being nearly as watchable without him.
