It seems like only yesterday that Wanda gave birth to Billy and Tommy. Given how WandaVision plays musical chairs with reality, she might as well have. But in flagrant disregard of the laws of nature, the twins have already grown into bright-eyed boys. Kids grow up so quickly, don't they? But the growth spurts of Billy and Tommy are downright ridiculous. What isn't ridiculous, however, is the casting logic behind Billy's current actor.
For the moment, Billy is played by Julian Hilliard. He has starred in The Haunting of Hill House, Color Out of Space, and Penny Dreadful: City of Angels. Hilliard is also set to appear in The Conjuring: The Devil Made Me Do It.
Since WandaVision spices up its sitcom satire with mild horror elements, it makes sense that Julian Hilliard is currently filling Billy's technicolor sneakers. Despite his young age, Hilliard has a lot of experience playing scared children in terrifying scenarios. However, since Billy has already been through several actors who represent the character at different ages, it's probably only a matter of time until someone else fills the role.
