My friend is looking for a movie from 90s; he remembers two details only. In this English-language B-movie thriller, the female protagonist moves into an apartment and begins an affair with her neighbor. During an intimate scene, the camera angle shifts disturbingly toward the inside of a closet, where a camera is likely hidden. Because of this, the name Adam Nelson has stuck in his mind regarding this movie, but checking the actors on IMDb didn’t help, and when I enter the same information in the Characters tab, nothing comes up.
It is not a B movie, but any chance it is “Sliver” (1993)?
Young, beautiful woman moves into an apartment building, affair with male neighbor, kot of hidden cameras.
