Friday Disney Parks posted two videos. The first is a featurette looking at the creation of the Haunted Mansion. This is to mark the attractions 45th Anniversary this year. Seems a little late to me, especially since the Nightmare Before Christmas overlay opened Friday (it is mentioned at the end of the video). Then a commercial for Halloween Time at Disneyland Resort.
