When it comes to car chase scenes, the one that is always highlighted, and for good reason, is from Peter Yates’ 1968 action thriller Bullitt starring Steve McQueen... but some eight years later, the city of San Francisco was replaced by Montreal, Quebec in this little known Italian production with quite the epic speedy sequence of its own, Shadows in an Empty Room (1976), directed by Alberto De Martino. Fusing this touch of Bullitt with a Dirty Harry style storyline – hence why it is called Blazing Magnum in some markets (including the UK), while also including a hint of the ever popular at the time 70s giallo for some murder mystery elements, the narrative follows gritty, hard as nails Ottawa cop Capt. Tony Saitta (Stuart Whitman) as he dispatches some bank robbers in his own city... before getting the tragic call that his much younger sister, Louise (Carole Laure – Sweet Movie), who lives in Montreal, has died under very suspicious circumstances.
