The Scream Team(2002)

Eccentric Frank Carlyle ran a horror shop in small-town Steeple Falls, which takes pride in and profit from its Halloween traditions. Frank's widower grandson Richard grudgingly returns there from Boston with his own kids, bright Ian and bratty Claire, to settle the inheritance. Ian discovers great-grandpa's house is really haunted, and not just, as legend holds, by historic owner Zachariah Kull, who was burned on the stake.
