Neil Miller is Laura's second husband, Charlie Calvin's stepfather, and Lucy's father in The Santa Clause franchise. He was briefly a minor antagonist in the first installment with his wife but became a supporting character in the remaining trilogy.
By the second film, Neil is on friendlier terms with Scott, with him even being the adoptive uncle of their daughter, Lucy. However, they will occasionally butt heads, as seen as they did in Principal Newman's office while occasionally having conflict with him at times. He also became friends with Scott's current wife and Charlie's ex-principal, Carol, which Carol's parents find strange.
