Dragonwyck (1946) Joseph L Mankiewicz.

 Fig 1. Scruffed up, possibly hopped up.

Personal favourite for unintentional hilarity.  Mustaches:  on some men it looks like they chose a peel-off from an East German disguise kit and for other men it is an indisputable part of their entire physical and psychic being.  The latter:  Vincent Price, who I contend is borderline unrecognizable without his.  Luckily, by the end of this movie, he is scruffed up enough (see fig. 1) to start to look familiar.  Price marries "farm-bred" dutifully religious Gene Tierney -- wait, sorry... I don't buy it.  Gene Tierney?  The gorgeous, urbane brunette of Laura?  Anywhat, she marries Price who has a phobia of the handicapped stemming from a tragedy experienced earlier in his life.  He's an elitist atheist landowner (check out the size of that crest on his smoking jacket!) harbouring general disgust for average folks.  In his own words: "I will not live by ordinary standards!  I will not run with the pack!  I will not be chained into a routine of living that is the same for others!  I will not look to the ground and move on the ground as the rest.  So long as there are mountaintops and clouds and limitless space."  OK, I guess that sounds a little Nietzschean although at least he has a vision.  Tierney does lacework, gossiping with Peggy her crip Irish maid about what is WITH this guy (her own husband) until she gets enough nerve up to see just what he is up to, keeping himself occupied in a small room in a tower of his (castle?).  When she breaks in, he confesses he has turned into "a DRUG ADDICT!" (As elitist atheism is prone to induce).  Well, instead of Tierney doing the Christian thing and perhaps trying to redeem her husband, she chastizes him.  The movie implies that there are just some dirtbags who are not worth it but luckily she has another potential love interest, tastes-like-cardboard Dr Jeff Turner, played by Glenn Langan.  You know, sometimes I throw my dog a piece of slimy grey deli meat that's been in the fridge too long and this is kind of similar.  We both love the rotten ham!
