Top 5 Losing Their Mind Films

To be eligible the lead had to be losing their mind, not a co-star (Full Metal Jacket is knocked out of the running).  That lead has to start the movie somewhat sane and then unravel as the story progresses (The Machinist is out).  Also, if alcohol or drugs are involved the film is ineligible (Scarface).
