For more than 25 years, Canadian filmmaker David Cronenberg has been making movies about man's fatal attraction to the extreme -- be it electronic (''Videodrome"), scientific (''The Fly"), medical (''Dead Ringers"), transgender (''M. Butterfly"), narcotic (''Naked Lunch"), erotic (''Crash"), virtual (''eXistenZ"), or psychological (''Spider"). His latest movie, ''A History of Violence," is something of a change-up. A mild-mannered, small-town fellow is accused of having gone to grisly extremes in the past.
The film has the perverse intelligence of Cronenberg's other movies. It's not his best, but it is certainly his most accessible, least stagy work, obeying the laws of chronology and serving up characters whom we recognize as people. The movie's brilliance resides in its use of cinematic convention to shatter an illusion of social normalcy.
