Jake Lacy Unpacks Peter Irvine’s Dark Psychology in All Her Fault

Jake Lacy reveals the complex motives behind his chilling character in Peacock’s thriller All Her Fault. Peter Irvine commits unthinkable acts, including swapping his dead baby with another’s. Lacy explains he worked to find the humanity in Peter’s monstrous decisions.

The actor delved deep into his character’s backstory and psychology. He aimed to understand Peter’s fear and self-loathing rather than simply playing a villain.

Finding the Human Fear Behind a Monster

Lacy’s biggest challenge was legitimizing Peter’s horrific choices. He had to find a way to believe in Peter’s twisted logic. This meant seeing the world from Peter’s narcissistic and fearful point of view.

According to The Hollywood Reporter, Lacy identified Peter’s core trait as a paralyzing fear of failure. The character is filled with self-loathing and cannot bear any threat to his self-image. This fear is hardwired into his personality from a young age.

This explains early actions, like letting his sister take blame for his brother’s accident. Peter seizes any opportunity to avoid responsibility. He must maintain his own illusion of being the “white knight” in his mind.

The Baby Swap and a Life Built on Lies

Lacy breaks down Peter’s mindset during the pivotal baby swap. Peter genuinely believed he was in shock after the car accident. He thought he could protect his wife Marissa from grief by replacing their dead son.

He incorrectly assumed the other baby’s mother was also dead. From his perspective, this horrific act was a way to erase a bad moment. He saw it as a weight he would carry so his wife wouldn’t have to suffer.

This reveals Peter’s God complex and narcissism. He believes he can control reality and decide how others should experience life and grief. This delusion ultimately unravels his entire life.

Even after all his lies are exposed, Peter believes life can return to normal. He thinks those closest to him will eventually see things his way. His inability to admit guilt is his ultimate sin.

Jake Lacy’s performance provides a terrifying look into a man destroyed by his own fear. His character analysis of Peter Irvine shows that true monsters are often born from an inability to face reality.
