Mainstream films are easy to recommend to people. They’re usually formulaic, work within clear parameters and they’re not controversial. Most people, when viewing such film on someone else’s suggestion, are left with a fairly simply choice. Did they like it or not? Whatever the outcome, no feathers are ruffled. No one looks at you askance afterwards and says “why the hell did you think I’d like that piece of shit”? If something like this happens, then you have clearly not recommended a mainstream film. Perhaps you’ve suggested something that’s a little more of an acquired taste. Something niche, from a very specific sub-genre. Which brings me neatly to Blazing Magnum AKA Strange Shadows in an Empty Room (1976). The US title gives the impression that this film is a hard boiled cop thriller, like so many others that followed in the wake of Dirty Harry. But there’s a clue in the European title. Yes, this movie has more than just a whiff of a giallo about it.
