William Edward Lenz (Also known as Billy Lenz) is an antagonist in the 2006 remake of Black Christmas. The character is based on the unnamed main antagonist commonly referred to as Billy, from the original film. He is portrayed by Cainan Wiebe as a child and Robert Mann as an adult. 


Tortured ChildhoodEdit

Billy Child

Billy as a child.

Billy was born in 1970 to Constance and Franklin "Frank" Lenz under the name William Edward Lenz. Born with a rare liver disease that made his skin yellow, he was despised by his mother who psychologically and physically abused him. Billy's father, however, was very warm-hearted and pampered his son, and tried to bring happiness to him whenever his cruel wife tried ruining events like Christmas. It could be said that Billy's father was quite possibly the only positive influence in his life. This positive influence, however, sadly was not to last. Mrs. Lenz was unsatisfied with her husband, and at an unknown period of time, she took a new lover.

Whether Billy knew about the affair is unknown. Then on Christmas in 1975, when Billy was five years old, Mrs. Lenz and her lover murdered her husband with a claw hammer, which Billy witnessed while hiding underneath the bed. His mother soon noticed him hiding and locked him in the house's upstairs attic so that he would never tell anyone about the murder.

In 1982, Mrs. Lenz discovered that she was unable to conceive a child with her lover-turned-husband due to his impotency. Determined on conceiving a child, she entered the attic and raped Billy. Even though Billy was 12 years old at the time, Mrs. Lenz becomes pregnant with Billy's child and that same year she gave birth to a girl who she named Agnes, who, despite being inbred, was treated like a little queen by Billy's mother and her lover, the love that Billy was denied by his mother. Mrs. Lenz would never tell her new husband about the "affair", making him believe that he was the child's father.

Murdering His MotherEdit


Billy on the night he killed his mother and her lover.

Nine years later, on Christmas Day in 1991, all the years of pent-up rage from his abuse and neglect finally caused Billy to snap. Escaping from the confines of the dark attic, Billy viciously attacked Agnes while she was in the kitchen, covering her head with plastic as he proceeded to disfigure her face with a knife. Hearing her screams, Billy's mother and stepfather rushed into the kitchen in time to witness the evil Billy removing one of Agnes' eyes and devouring it.

Noticing his mother, Billy began taunting her by saying that Agnes was "his family now". His step-father then charged at him but was quickly killed when Billy impaled his head with a sharpened Christmas decoration. Billy then grabbed his mother, the source of all his years of suffering and unhappiness, wrapped Christmas lights around her neck and dragged her across the blood-soaked floor. Grabbing a rolling pin, Billy then proceeded to viciously beat her to death with it. The source of his fury now dead, he then proceeded to tear off chunks of his mother's flesh with a cookie cutter, placing the pieces in the oven.

A little while later, the police broke into the house, revealing the carnage that Billy had caused. They found Agnes crying in pain in a pool of her own blood, surrounded by the mutilated corpses of her mother and "father", and nearby Billy sat cheerfully eating the freshly-baked "cookies" made from his mother's flesh.


Arrested for his crimes, while Agnes was sent to an orphans' asylum, Billy was later found by the courts to be criminally insane and was sent to a psychiatric facility where he remained for the next 15 years. During his stay there, Billy underwent thirteen failed escape attempts from the psychiatric facility, all of which took place on Christmas Eve. Sometime during this span, the Lenz home was sold and turned into a sorority house. The new inhabitants of the Lenz family house knew about the Lenz family and the murders committed by Billy and for reasons unknown they began regularly sending him presents each Christmas.

Escape and Killing spreeEdit

On December 24, 2006, approximately fifteen years after murdering his mother and stepfather, Billy finally managed to escape the facility, killing one of the security guards with a candy cane which he had sharpened into a shiv. As he made his escape Billy came across a man dressed as Santa who regularly made visits to the facility in order to cheer up the places residents, he slaughtered the man and stole his clothes, walking out of the facility undetected.

After his escape, Billy began his trek back home. Managing to get to a phone, he called his old home, rambling and harassing the house's new residents until one of the sorority girls, Leigh Colvin taunted him. Enraged, Billy threatened to kill them all before hanging up. Arriving at his childhood home he proceeded to murder two of the house's inhabitants, Heather Fitzgerald and Barbara MacHenry. Entering the house, Billy made his way to the attic, the place he was imprisoned for most of his childhood.

Emerging in front of the houses sole survivors Kelli and Leigh, reuniting with Agnes, who is revealed to be just as murderous and insane as her father as well as the one responsible for the murders of most of the house's inhabitants. Both Agnes and Billy then converge on the two survivors, with the two killers managing to knock both themselves and Kelli into the empty space between the walls of the house. Before they are able to finish her off, Kelli is saved by Leigh, and together they set the house on fire, leaving both Agnes and Billy to burn to death in the blazing inferno.



Billy Lenz's Death

Billy and Agnes manage to escape the burning house, with Billy left seriously burnt from the fire. Together, the two make their way to the hospital, where Kelli and Leigh were staying. Entering the hospital, Billy slaughtered the morgue attendant, leaving Agnes to kill the two survivors. After murdering Leigh, Agnes attempted to do the same to Kelli but was subsequently electrocuted by Kelli with a defibrillator, killing her.

Entering the room shortly after this, Billy, enraged by the death of his daughter, pursued Kelly through the hospital. Seemingly cornering her at the stairwell, the two engage in a brief fight, with Kelli managing to knock Billy off the railing. Plummeting to the ground below, Billy is impaled on top of a Christmas tree used to decorate the facility, finally putting an end to his rampage.


His bloody rampage which started on December 25, 1991, and ended with his death on December 24, 2006, at the age of 36 years old, during his killing spree Billy Lenz brutally murdered seven individuals and horrifically disfigured his daughter/sister Agnes on Christmas in 1991, this incident left Agnes psychologically imbalanced and disturbed so much that this would also lead to her becoming a serial killer like her father, which ended in her death on December 24th in 2006.

Personality Edit

From an early age, Billy Lenz was subject to severe physical and psychological abuse at the hands of his mother, who hated him due to his appearance. This abuse would last into Billy's early adulthood, and as a result, gave him a deep-seated fury towards his mother and humanity. The only positive influence on the young Billy was his father, who treated him with the kindness and love he would never receive from his mother. After witnessing his mother and her lover murder father. The resulting imprisonment, and the later rape he suffered at the hands of his mother deeply shell shocked Billy.

Most of the horrific events in Billy's childhood occurred during the Christmas season and, as a result, he became obsessed with the holiday itself, which he equated to all the suffering he endured. This is best shown during the phone call sequence where he reveals a very twisted view on the holiday itself.

Billy also seems to have a complicated relationship with his sister/daughter Agnes, though he does display something resembling jealousy at the love and attention she was given as a child by his mother, which resulted in his disfiguring her to make her look as ugly as what their mother thought of him as. However, after reuniting with her as an adult, they both display mutual respect for each other to the extent where Billy is visibly upset when she is killed.
