I definitely don't have a solution for "de-siloing" the university, but I also want to pose another question. If we don't provide filmmaking training for public historians, why does the field term documentarians as part of our community? Do we actually see them as historians or associate them with ahistorical entertainment? Entertaining history ((or pop history as you term it)) expands and engages audience--the main tenets of public history work. Once again, the professional history world decides who is "in" based upon their usage of traditional mediums.
