Shock was initially released as Schock and later as Beyond the Door II and was director Mario Bava (A Bay of Blood)’s last film. The film follows Dora, played by Daria Nicolodi (Deep Red, Opera), who has just moved back into her old house following a mental breakdown and the mysterious death of her first husband. Together with Dora are her new husband Bruno (John Steiner, Tenebre), who is away a lot due to his job, and young son Marco (David Colin, Jr., Beyond the Door).
Upon moving in strange things start to happen to both Dora and Marco as they are visited by the ghost of Carlo (a.k.a. the dead husband/father). It is quite early on in the film that Marco becomes possessed by Carlo and starts to terrorise his mother in very adult ways. Along with Marco’s strange behaviour Dora starts to hallucinate and regain some memories about Carlo and the night he died and her part in it. Before being too harsh on Dora, it must be pointed out that Carlo was far from the model husband, rather he was an abusive drug addict.
The soundtrack to Schock is impressive and utilises several different techniques to build suspense including the ubiquitous violins but also syncopated off-kilter drumbeats. Although the plot of Schock is pretty simple it is extremely well done. There is an attempt at the old ‘is she going insane or is it supernatural’ troupe however I think it is clear from the scenes with Marco that it is of the supernatural persuasion. It is inevitable that comparisons will be drawn between Schock and The Exorcist – both being films made in the 1970s about child possession, however they are very different. What sets Schock apart from a lot of possession films is that it is a ‘human’ (albeit dead) that is possessing rather than an all-powerful demon or the devil.
Although Bava is well known for his Giallo genre films (hence the tag), I don’t know if I would consider Schock to be an example of that genre, if nothing else the title and plot are not convoluted enough to be classic Giallo. Despite this I thoroughly enjoyed the film and would recommend it, particularly if you don’t have much brain power to spend!
Fun Fact: The alternative title of Beyond the Door II was chosen to link to a previous film by Ovidio G. Assonitis with the spurious link that David Colin Jr. plays a possessed child in both films.
