What ghost films have been made by Disney?
A recent cartoon version of the Dickensian ( Christmas Carol) might be one. somewhat oddly no real supernatural horror films ( not very family-friendly) were made when Walt was at the helm ( he died in l966) Possibly related, neither of the TWO Disney television programs ( Wonderful World of Color- and Mickey Mouse Club) ever had any Christmas specials! Mickey Mouse Club was unusual for a juvenile daily program- as it originally was, in that it did not follow the calendar, unlike , for example Captain Kangaroo and Howdy Doody- if they did almost certainly they would feel obligated to have a Christmas episode. Nor did Disney ever invent ( He had a good music department and a record label!)- any original Christmas songs.
