Hold back your excitement, Giallo fans, what we have here is a truly sneaky piece of false advertising.
This great, sinister and creepy trailer for "Strange Shadows.." is actually a masterful piece of misdirection. In fact, it is a retitling of the Eurocrime thriller "Blazing Magnums" which is actually a cops n' robbers piece featuring car chases, punch-ups and gunfights a-plenty. It is not a slasher/giallo movie at all, but is dishonestly marketed as such for its Western release, a fairly common practice for Eurocrime films at the time.
Pretty sneaky, sis..
