1. The original title was Halloween House, but eight years and about 11 writers later, it became a much less scarier, more kid-friendly movie so a name-change was in order.

2. Production initially started out in Salem in November before finishing on sound stages in Los Angeles. Great for fall foliage. Not so great for decorations.

"The thing I love about the Salem stuff is when we went there, it was getting into Christmastime, and so people were starting to put up their Christmas ornaments," Tobias Jelinek, who played the bully Jay, told E! News. "They were having to pay them out block by block to take down all their decorations so we could get all the Halloween stuff."
