Movies - 28 Days Later Rage Virus A question

[Alicia]

There is a question for those of you who have seen the 28 days film about the virus that transmits in a drop of blood and causes those infected turn have instant full blown murderous rage that is permanent. They can not be talked down, They will basically run round after people That are not infected and try and kill them but mainly they just pass on the virus until they are shot or dead from starvation. The film was set in Britain. It starts off with animal activists that brake into a lab try to rescue one of the monkeys thats caged thats infected naturally thats how it starts and before long all of Britain is infected, the film is based on a few survivors of the virus.

Granted its a film its not real. but is there any sort of inhibiter or substance/chemical out there that would cause that sort of reaction in an individual or cause instant violent psychotic like behavior. Im not talking about alcohol induced rage as that is gradual. Any responses I would like to hear.
