Children Buried in Fireplace w/ Lion's Head

by Jessica

Trying to remember the name of a movie about a man that teaches paranormal activity.

He takes his students up to a house that belongs to a man with a lot of children (or he loves chldren, or both). Statues of children are everywhere - over the headboards, etc.

I can't remember if his children had died or he killed them, but it turns out they are all buried in the fireplace where a lion's head would come in and out.

Does anyone know what movie I am talking about?
