Mockumentary set in medieval England with no explanation as to why or how a camera crew is there
A lot of people have mentioned monty python and the holy grail on this post which is accurate but I was envisioning more of a the office/what we do in the shadows type sitcom complete with talking heads and will-they-or-won’t-theys and with the technology that allows the mockumentary genre to exist going completely unquestioned by the entire cast despise it not occurring anywhere else in the otherwise realistically portrayed setting
