Patrick Pryor’s review published on Letterboxd:
I'm always a sucker for insane stunt work that really knocks the air outta my lungs and makes me fear for human life and provides a rush so pure and shocking I want to jump kick the ceiling. Belmondo delivers with scenes of subway surfing, Parisian rooftop slipping, and helicopter rappelling derring-do. Quelle horreur! Some of the police procedural exposition feels a li'l slow, especially following an extended showstopper of real moving bodies in danger, but at least the camerawork looks as slick as any giallo thriller. I especially loved a sequence where a knocked locker mirror swings back and forth framing both the killer and victim in struggle. Super chouette!
I also love movies that feel like a documentary of their own making. Especially in more obscure or lower budget pictures, I peep locations and people that I would never encounter in my broke jerk cinetrog life. I wanted to crawl through the Fear Over the City's frame and live on those Parisian rooftops and back alleys and bridges stuffed with gorgeous architecture. Statues and balconies and sprawling views of the city I've never seen in a French film before. Travel is cheap in a movie theater!
