Obsessions (aka Bezeten - Het Gat In De Muur) (1969)

When a painting falls off the wall in his apartment, a medical student (Dieter Geissler) discovers a small hole in the wall. Peeking through it into his neighbor's apartment, he witnesses what appears to be a sex  and torture crime. But instead of calling the police, he finds himself pulled into the sordidness of it all. Directed by Pim De La Parra, this exploitation film doesn't make a lick of sense. People behave in illogical ways and there are an abundance of loopholes that are frustrating. For an exploitation film, it has some talented people behind the camera. A young Martin Scorsese gets credit as one of the three screenwriters, the film editor is Henri Rust who edited CHILDREN OF PARADISE and WAGES OF FEAR and the underscore is by the great Bernard Herrmann. Herrmann's score infuses the film with a needed sense of dread and mystery. The film's gory finale is telegraphed and I looked away just in time. The acting is stiff and that may be because English is not the native language for the majority of the cast. It's a Dutch film in the English language. Only Alexandra Stewart (DAY FOR NIGHT) as Geissler's girlfriend manages to give something resembling a performance. With Tom Van Beek, Donald Jones, Elisabeth Versluys and Marijke Boonstra.
