In the style of Wiseman ?

Recently deceased: moviemaker, Frederick Wiseman, and actor, Robert Duvall.

Duvall was in LOTs of TV shows and movies - each role seemed to be completely unique although all feature that eerie penetrating gaze. One of my favorite Duvall appearances was on The Outer Limits two parter called: The Inheritors. Duvall plays a relentless government investigator of weirdness and strangeness with his trademark intensity.

definitely NOT Fox Mulder

Wiseman made documentaries that could also be eerie. Every once in a while his latest film would get played on PBS, one time and that was it. There aren't any full examples on the internet but I do remember this from Belfast, Maine (packing sardines scene):

don't let me hear any whining about how hard you work

In addition, Youtube recently served up this pretty freaky little movie:

flamboyant in Norway

No narration, not much in the way of explanation, just scenes of life, in this case with weird and photogenic backgrounds and somewhat obnoxious humans - It reminds me of a Wiseman movie !
