Here’s Mike Hammer at his glorious best.
There’s a lot in this movie. A 1951 Jaguar XK 120 Roadster. A young Cloris Leachman naked in a raincoat. Mike Hammer like he’s a deviant James Bond. Science.
Check out the long continuous shot in the boxing gym.
You can see (or imagine) this movie influencing Star Wars (the intro), Repo Man, and maybe even Pulp Fiction.
Check it out.
