Isaac Izzard

Issac Izard is the main antagonist of the novel The House with a Clock in its Walls and its movie. He is an all powerful and evil warlock, the house's original owner and Johnathan's arch-nenesis.

Isaac Izard was a resident of New Zebedee, Michigan, and a practicing warlock who, with his wife, Selenna, created the Doomsday Clock. The two once lived at 100 High Street, now owned by Jonathan Barnavelt.

He was protrayed by Kyle Maclachlan, who also played King Claudius in Hamlet, Cliff Vandercave in The Flintstones, Killer BOB in Twin Peaks, Earl Raymond Diggs in HBO's Tale From the Crypt, Donald Love in Grand Theft Auto and Calvin L. Johnson in Agents of Shields.

Role In Film
Originally, Isaac Izard and his friend Jonathan Barnavelt were a magic duo, touring the country and performing their shows, using real magic without anyone knowing. Then the Second World War broke out, and Isaac enlisted in the military. The horrors he saw in the war turned him bitter and spiteful of humanity, which was heightened one fateful day. His unit was ambushed in battle, and he fled into the Black Forest, where he wandered for days. He used every spell he could think of with one thought in his mind: to undo all of it, all the horror and hardship and suffering he had been through. This had the effect of summoning the being who gave him the means to do just that, the demon prince Azazel. Azazel and Isaac made a deal which gave Isaac the blueprints for the Clock. Upon returning home, he married the wicked witch Selenna, and they shut themselves away, until Isaac’s death trying to cast blood magic, which caused a blast on energy. Before he died, he hid the Doomsday Clock in the walls, made so when the time is right, he can reset the world to the beginning of time, and then stopping it to continue one more.

About a year later, Lewis Barnavelt goes to live with his uncle after the death of his parents in a car crash.
