A man is searching for love and is a rather shy person, rather overweight.  He works in an office building.  He meets a woman and pays her to date her.  Eventually they develop a romantic relationship, however she dies from drug overdose.  He keeps her body, having sex with it.  Causes quite a smell eventually, and the neighbors get bothered.  I didn’t recognize any famous celebrities, and it was a rather weird movie.  I think it was made in the last couple of decades.  He was actually considered a nutcase, in the beginning and end of the film.  It was in color, and it wasn’t a creepy movie as much as disgusting at the end.  It was nonetheless artistic.
