Coming out of the theater after watching A History of Violence, I can't help but think I was watching The Incredible Hulk. Centered around a man whose past has come to haunt his quiet Indiana life, we discover that under dangerous circumstances, he becomes another man, able to respond to danger instinctively. It's a compelling story with the first half of the film built around whether he is or is not from a violent past. Once we discover the truth, we learn about how he will deal with his family's discovery and whether who he was will now endanger what he has struggled to become.
But for my money, the most intriguing arc lies in his wife, Edie, a woman who seems completely from her peaceful, rural environment. While she responds with shock at the discovery of her husband's true nature, her accommodation of who he "is/was" presents the film's greatest intrigue.
At first, she is confused and disgusted; then she instinctively defends their family by covering for him with Sam, the policeman. But what made the story fulfilling was their confrontation on the staircase. After getting rid of Sam, she tries to leave the room and Tom goes after her, nearly choking her. This was startling by itself, but it unfolds into a fit of seeming passion as they grab and slap each other on the stairs. It's a melee that morphs into a pool of lust and punishment (to each other and to themselves), a stark contrast to their earlier sexual roleplay of unrequited adolescence and innocent love. On the staircase, with every cut and camera move, we observe a man and woman whose identities we're unsure of - is it Tom, the husband, or Joey, the murderer choking her; is it Edie as the sickened wife or as a woman who is drawn to his animal qualities.
By film's end, it's not clear if she will ultimately accept him (thank you, Mr. Cronenberg!), but we get the sense of where her heart is moving - after all, where she comes from, loyalty is the ultimate virtue, and they take care of their own.
